Depression

Depression is a mental health condition that can affect mood, thinking, energy, sleep, appetite and daily functioning.

It is more than a passing low mood and can make work, relationships and self-care feel difficult. Depression can look different from person to person, and support is available even when you cannot identify a clear reason for feeling this way.

Low mood, fatigue, loss of appetite, loss of libido and memory problems are very common presentations of depression. Feeling anxious, irritability and unintentional weight loss or weight gain can also occur. Some people withdraw from others, lose interest in usual activities or find it hard to make decisions.

If you are thinking about harming yourself, feel unable to keep yourself safe, or have made plans to end your life, contact emergency services or go to the nearest emergency department now. If possible, tell someone you trust and do not stay alone.

Depression does not have one single cause. It can arise through a mix of biological vulnerability, stressful experiences, loss, relationship difficulties, long-term illness, pain, substance use and patterns of sleep or daily routine.

A difficult event may be relevant, but its absence does not make symptoms less real. A clinician can also consider whether physical health conditions or medicines could be contributing to changes in mood or energy.

Symptoms may build gradually or follow a major change or period of stress. They can fluctuate through the day and may improve with treatment, practical support and time. Without support, depression can narrow routines and make reaching out feel harder.

Keeping a brief record of sleep, mood, appetite, activity and difficult thoughts can help you and your clinician notice patterns and judge whether a plan is helping.

A personal or family history of depression, ongoing stress, isolation, trauma, caring responsibilities, long-term health problems and problematic alcohol or drug use can increase vulnerability. Major life changes can also place extra strain on coping.

These factors do not determine what will happen to a person. They provide useful context for planning support, reducing pressures where possible and recognising symptoms earlier.

Diagnosis is based on a confidential conversation about mood, thoughts, physical symptoms, daily life, safety and how long changes have been present. A GP or mental health professional may use questions to understand severity and identify support needs.

The clinician may also ask about sleep, alcohol or drugs, past episodes, medicines and physical health. Blood tests or other checks may be considered when another medical cause could be contributing to similar symptoms.

Treatment is tailored to the person and may include talking therapy, changes to daily routine, support for practical stresses and antidepressant medicine. A clinician can discuss expected benefits, possible side effects and how follow-up will work.

Medication is not the only option, and therapy is not only for severe symptoms. The right plan may combine approaches and change over time. Do not stop prescribed antidepressants suddenly without discussing it with the prescriber.

Choose a manageable starting point: regular meals, a consistent wake time, a short walk, or one conversation with someone supportive. Breaking tasks into small actions can reduce the pressure created by a long to-do list.

Let a trusted person know when symptoms are worsening. Keeping appointments, taking medicine as prescribed and bringing questions to follow-up visits can make treatment easier to adjust.

Depression can affect employment, education, relationships, physical health and personal safety. Suicidal thoughts, self-harm, severe inability to eat or drink, or losing touch with reality need urgent professional help. Emergency services are appropriate when there is immediate danger.

Depression cannot always be prevented, but early support can limit how much symptoms disrupt life. Protecting sleep, staying connected, addressing alcohol or drug concerns and seeking help during prolonged stress can be useful parts of a prevention plan.

A GP can be a helpful first contact for mood changes, physical symptoms and referrals. A mental health assessment offers time to explore symptoms and treatment choices in more depth. Use urgent services if safety is a concern.
