What should you know about emotional and mental exhaustion?

You may feel drained by ordinary decisions, struggle to focus, become irritable or detached, sleep poorly, or find work and relationships harder to manage. Ongoing stress, grief, caregiving, low mood, anxiety, poor sleep, and burnout can contribute. Physical causes also deserve consideration: anaemia, dehydration, COVID-19, coeliac disease, chronic kidney disease, and chronic fatigue syndrome can all be associated with fatigue, but exhaustion alone cannot identify a specific condition. Alcohol use can worsen sleep, mood, and energy.

Reduce non-essential demands for a short period and keep a simple record of sleep, mood, energy, food, fluids, alcohol, medicines, and major stressors. Use regular meals, enough fluids, daylight, gentle movement, and a consistent sleep routine where these are manageable. Tell someone you trust what you are experiencing. Arrange a GP appointment if symptoms persist, recur, or interfere with work, study, self-care, or relationships; a clinician can review mental health and physical contributors together.

Seek urgent help for thoughts of suicide or self-harm, feeling unable to stay safe, severe confusion, hallucinations, chest pain, severe breathing difficulty, fainting, or sudden neurological symptoms. Ask someone to stay with you and contact local emergency services if immediate danger is present. Prompt medical review is also sensible for rapid unexplained decline, persistent vomiting, severe dehydration symptoms, or inability to perform basic daily tasks.

Ask what symptoms and timeline matter for assessment, whether your sleep, mood, medicines, alcohol, or stress may be contributing, and whether blood tests or other checks are appropriate. Discuss support options, work adjustments, and a clear follow-up plan.
