Why Am I Suddenly So Emotional and Forgetful? Understanding Menopause, Brain Fog, and Mood Changes
Many women entering perimenopause or menopause describe feeling unlike themselves. They may notice increased emotional sensitivity, anxiety, forgetfulness, difficulty concentrating, or a sense of mental “fog” that feels difficult to explain.
For some women, these changes can feel sudden and confusing, particularly when they occur alongside work stress, parenting responsibilities, relationship pressures, or other major life transitions. Many begin wondering why they suddenly feel overwhelmed so easily, why their memory seems different, or why they no longer feel as emotionally resilient as they once did.
While every woman’s experience is different, emotional and cognitive changes are extremely common during perimenopause and menopause. Hormonal fluctuations can significantly affect mood, memory, sleep, concentration, and overall emotional wellbeing. Understanding these changes can often help women feel more informed, supported, and less alone in what they are experiencing.
What Is Perimenopause and Menopause?
Perimenopause refers to the transition leading up to menopause, when hormone levels, particularly oestrogen and progesterone, begin fluctuating. This stage can last several years and often begins during a woman’s 40s, although some women experience symptoms earlier.
Menopause is officially diagnosed after 12 consecutive months without a menstrual period.
Although menopause is often associated with physical symptoms such as hot flushes or night sweats, many women are surprised by the emotional and cognitive symptoms that can emerge during this time.

Why Do Emotional Changes Happen During Menopause?
Hormones play an important role in regulating mood, stress responses, sleep, and emotional processing. As hormone levels fluctuate, many women notice changes in how they respond emotionally to everyday situations.
Women may find themselves becoming more irritable, tearful, anxious, emotionally reactive, or overwhelmed than usual. Situations that once felt manageable may suddenly feel exhausting or emotionally draining. Some women also report feeling emotionally flat, disconnected, or mentally exhausted.
These experiences can feel particularly confronting for women who have always considered themselves calm, capable, or emotionally resilient. However, these changes are not uncommon. Hormonal fluctuations can affect the nervous system, emotional regulation, and stress tolerance.
Sleep disruption, chronic stress, burnout, and the demands of daily life can also intensify emotional symptoms during this stage.
Understanding Menopause and Brain Fog
One of the most reported symptoms during perimenopause and menopause is brain fog.
Brain fog is a term used to describe cognitive difficulties such as forgetfulness, trouble concentrating, mental fatigue, losing track of conversations, difficulty finding words, or feeling mentally slower than usual.
Many women describe feeling scattered, forgetful, or unable to think as clearly as they once could. Some become concerned that something more serious may be wrong, particularly when memory lapses begin affecting work, daily tasks, or confidence.
Research suggests that changing hormone levels, particularly declining oestrogen, can affect memory, attention, and cognitive functioning. Brain fog can also be worsened by poor sleep, stress, anxiety, emotional exhaustion, and mental overload.
For many women, these symptoms improve over time, particularly with appropriate support and lifestyle adjustments.
Why Sleep Difficulties Can Make Symptoms Worse
Sleep changes are another significant factor contributing to emotional and cognitive difficulties during menopause.
Many women experience interrupted sleep, difficulty falling asleep, waking frequently during the night, or waking feeling exhausted despite spending enough time in bed. Night sweats and hormonal fluctuations can further disrupt sleep quality.
When sleep becomes chronically disrupted, it can affect concentration, emotional regulation, memory, stress tolerance, and overall wellbeing. Women may find themselves feeling increasingly emotionally reactive, mentally fatigued, or overwhelmed by tasks that previously felt manageable.
Over time, this can contribute to burnout, anxiety, and emotional exhaustion.
Why Menopause Can Feel So Overwhelming
Perimenopause and menopause often occur during an already demanding stage of life. Many women are simultaneously managing careers, parenting responsibilities, caregiving roles, relationship pressures, financial stress, ageing parents, or major life transitions.
When hormonal changes are layered on top of these existing pressures, it can feel increasingly difficult to cope in the same way they once could.
For some women, menopause may also intensify pre-existing mental health difficulties such as anxiety, depression, ADHD symptoms, trauma responses, or chronic stress. Others may begin recognising emotional struggles for the first time during this stage of life.
Many women describe feeling frustrated with themselves for no longer functioning in the way they previously did. However, these experiences are often reflective of genuine physical, hormonal, emotional, and psychological changes occurring simultaneously.
“I Don’t Feel Like Myself Anymore”
One of the most common experiences women report during menopause is feeling disconnected from themselves.
Some women feel less confident, less patient, or less emotionally stable than they once were. Others describe feeling mentally exhausted, emotionally sensitive, forgetful, or overwhelmed by everyday demands.
Because menopause symptoms are not always openly discussed, many women feel isolated or worry that they are “failing” to cope properly. In reality, these experiences are incredibly common and widely shared by women navigating this stage of life.
Importantly, menopause does not affect all women in the same way. Some women experience only mild symptoms, while others experience more significant emotional, cognitive, or physical changes that meaningfully affect daily life.
When Should You Seek Support?
Although emotional and cognitive changes during menopause can be common, this does not mean women need to simply tolerate significant distress unsupported.
Seeking support may be helpful if symptoms are affecting work, relationships, emotional wellbeing, sleep, confidence, or day-to-day functioning. Many women benefit from speaking with a GP, psychologist, or healthcare professional experienced in women’s mental health and menopause-related concerns.
Support may involve psychological therapy, medical treatment, lifestyle strategies, or a combination of approaches depending on each individual’s needs.
How Psychological Therapy Can Help During Menopause
Psychological therapy can provide a supportive space to better understand the emotional and psychological impact of menopause.
Therapy may help women manage anxiety, overwhelm, stress, burnout, emotional sensitivity, low mood, or difficulties adjusting to life changes occurring during this stage. It can also support women in developing healthier coping strategies, improving emotional regulation, and reducing self-criticism or frustration toward themselves.
For many women, therapy also provides validation and reassurance during a period that can otherwise feel confusing or isolating.
Importantly, therapy is not about “fixing” menopause. Rather, it can help women feel more supported, informed, and emotionally equipped to navigate this transition with greater self-understanding and confidence.

Frequently Asked Questions About Menopause
How do the hormonal changes of menopause affect the brain?
The brain contains hormone receptors for oestrogen and progesterone in several key regions including areas involved in memory, emotion, and cognition. Throughout a woman's reproductive years, these receptors receive a steady supply of hormones. During perimenopause, however, oestrogen levels begin to fluctuate significantly, and after menopause they decline. This means those receptors are no longer being adequately stimulated.
These hormonal shifts also influence the production and regulation of neurotransmitters such as dopamine and serotonin which are the chemicals that play a central role in mood, motivation, and mental clarity. For many women, this combination of changing hormone levels and altered brain chemistry can contribute to symptoms like brain fog, forgetfulness, low mood, and increased anxiety.
Can menopause trigger or worsen anxiety?
Yes. Fluctuating oestrogen levels directly affect the brain's stress response systems, which can make women more reactive to anxiety during perimenopause and menopause. Some women experience anxiety for the first time during this transition, while others find that existing anxiety becomes harder to manage. Sleep disruptions, which are common during menopause, can further amplify anxiety symptoms. Psychological therapy can be very effective in helping women develop strategies to manage anxiety during this time.
Is it common to feel irritable or angry during menopause?
Yes. Irritability and anger are among the most frequently reported emotional symptoms of perimenopause and menopause. Fluctuating oestrogen directly affects the brain's emotional regulation systems, lowering the threshold for frustration and reducing the capacity to manage stress. Many women describe feeling reactive in ways that feel foreign and distressing, particularly in close relationships. Understanding that this has a physiological basis can itself be reassuring, and psychological therapy can help develop practical strategies for emotional regulation during this time.
Is it normal to feel a sense of grief or loss during menopause?
Yes, and it is more common than many women expect. Menopause can bring up complex feelings about fertility, ageing and changing identity. Some women grieve the end of their reproductive years, even if they did not want more children. Others find that menopause coincides with other significant life changes like children leaving home, caring for ageing parents or shifts in relationships or career. These changes can compound the sense of loss. These feelings are valid and deserve proper acknowledgement and support.
Am I eligible for a Mental Health Care Plan (MHCP) to see a psychologist for menopause-related symptoms?
Yes, in most cases. A Mental Health Care Plan is issued by your GP and allows you to access Medicare-rebated psychology sessions. If menopause-related symptoms (such as anxiety, depression, low mood, or significant emotional distress) are affecting your daily functioning, you may be eligible. Speak with your GP and be clear about the psychological impact your symptoms are having. A diagnosis such as anxiety or depression does not need to be formally established first.
