Depression is a serious mental disorder that affects your feelings, thoughts and behaviour. It is characterised by a deep feeling of sadness and hopelessness and by losing interest in and pleasure from what you used to love. It affects daily life and can cause a range of emotional and physical problems.
The symptoms vary in severity, but often include persistent sadness, apathy, tiredness, irritability, disturbed sleep, changed appetite, difficulty concentrating and feelings of worthlessness or guilt. In serious cases there can be thoughts of suicide or suicide attempts.
Depression is caused by a complex interplay of genetic, biological, environmental and psychological factors. Life events such as trauma, divorce, moving house, changing jobs, a new child or stress can trigger it. Biologically, changes in the brain’s chemical balance, especially the neurotransmitters serotonin and noradrenaline, can play a role.
You can have depression in different degrees, from mild to severe. It is a serious disorder that you should take seriously and get help for if you cannot manage it yourself. And that is rarely possible with moderate to severe depression. It can reduce your quality of life considerably and in some cases be downright disabling.
It is a good idea to start with your GP and talk about the symptoms you are experiencing. The doctor can screen for depression and guide you towards treatment. The symptoms must have lasted at least two weeks, but often they have been there longer. They can just be hard to notice yourself, and so it is often someone close to you who sees the depression before you do.
It is important to be alert to suicidal thoughts: whether you carry thoughts of not wanting to live any more and perhaps have made plans to take your own life. If that is how you feel, contact the nearest psychiatric emergency department immediately, or call 112. That also applies if you have not made plans but are worried that you might do something impulsive.
Depression can affect people of all ages and all backgrounds. It knows no social or cultural boundaries. Some groups are more vulnerable, though. Women are diagnosed with depression more often than men, probably because of an interplay of biological, hormonal and psychosocial factors. Hormonal changes with menstruation, pregnancy, childbirth and the menopause can play a part.
The risk is also greater if there is depression or other mental disorders in the family, which points to a genetic vulnerability. If you have experienced trauma, stressful life events, chronic illness or substance abuse, you are likewise more exposed. Young people can be particularly vulnerable because of pressure from social media, study pressure and the work of finding themselves, and older people because of loneliness, loss of people close to them and worries about health and independence.
And then there is what I want to say to you directly: depression can affect anyone, no matter how "ideal" life looks from the outside. It says nothing about who you are. It is a complex disorder that requires understanding and treatment that fits you specifically.
