What should you know about reactive depression?

A relationship ending, bereavement, work difficulty, illness, relocation, or another major change can affect mood, sleep, appetite, energy, and motivation. You may also notice irritability, anxiety, tiredness, or difficulty concentrating. These symptoms can overlap with depression, so the trigger alone does not determine the diagnosis. A clinician considers how intense the symptoms are, how long they have continued, and how much they interfere with daily life. Some people sleep too little, while others sleep excessively; either pattern can leave you exhausted during the day. Symptoms may occur alongside insomnia or [Feeling Anxious](/symptoms/feeling-anxious/).

Keep a simple routine for meals, sleep, movement, and contact with trusted people. Break demanding tasks into small actions and avoid using alcohol or drugs to manage distress. Record changes in mood, sleep, appetite, and concentration so you can describe them accurately. Arrange a GP consultation or mental-health appointment if symptoms persist, worsen, or make work, study, self-care, or relationships difficult. Talking therapy may help you process the event and build coping strategies; a clinician can discuss whether other treatment is appropriate.

Seek urgent help if you think about harming yourself, feel unable to stay safe, or cannot manage basic needs. Contact local emergency services or go to an emergency department if danger is immediate, and tell someone you trust. Prompt medical assessment is also sensible for severe sleeplessness, rapidly worsening mood, confusion, or unusual bursts of energy with very little sleep.
