Mild depression symptoms: what to know

You may notice a low or flat mood, less pleasure in familiar activities, tiredness, slower thinking, or difficulty making decisions. Sleep may become disrupted, with difficulty sleeping or waking unrefreshed; some people sleep more and feel daytime sleepiness. Irritability or feeling anxious can also occur. Symptoms can be subtle but still interfere with work, relationships, self-care, or motivation. A symptom alone does not establish depression, because stress, medication effects, thyroid problems, anaemia, and other conditions can overlap.

Keep a simple note of mood, sleep, energy, appetite, concentration, and activities for several days. Arrange a GP consultation if symptoms persist, recur, or make routine tasks harder. Regular meals, gentle movement, daylight, a consistent sleep schedule, and contact with a trusted person may support recovery. Avoid relying on alcohol to change your mood. A clinician can discuss talking therapy, physical health checks, and whether treatment for depression is appropriate.

Seek urgent help now if you are thinking about suicide, harming yourself, or cannot stay safe; contact local emergency services or go to an emergency department. Arrange prompt medical assessment for a sudden major change in behaviour, confusion, hearing or seeing things others do not, or unusually high energy with very little sleep. Otherwise, book an appointment when symptoms are persistent, worsening, or affecting safety, work, eating, or personal care.

Which symptoms should I track, and could a physical condition or medicine be contributing? What support or talking therapy fits my situation? How soon should we review progress, and what should I do if my mood becomes unsafe?
