Condition : Depression
What is depression?
Feeling sad or low for a few days is normal. If you feel low for weeks or months, or it stops you doing your usual things, you might have depression.
Depression can affect people in different ways and symptoms can vary. Some may experience symptoms more often or severely than others, or for longer periods of time. The impact it has on everyday life is different for everyone.
Symptoms can include:
- low mood or feeling hopeless
- often tearful
- easily annoyed or impatient with others
- no interest in hobbies or things you used to enjoy
- worry or anxiety
- thinking about harming yourself or suicide
- moving or talking more slowly
- changes in appetite or weight
- unexplained aches or pain
- feeling very tired or having low energy
- lower interest in sex
- trouble sleeping or waking very early
When you have severe symptoms of depression and hallucinations and false beliefs (the symptoms of psychosis), this is known as psychotic depression.
Grief
Grieving is often confused with depression as it can have some of the same symptoms. Grief is a natural response to a loss that usually improves over time, while depression is an illness that lasts for a long period and may not have an obvious cause or starting point.
For some people, grieving can lead to depression.
What causes depression?
The trigger for depression will be different for everyone, and often there will be more than one.
Upsetting or stressful life events (bereavement, divorce, losing a job) are common causes depression. However, some people will describe a ‘downward spiral’, where one trigger leads to another. For example, a relationship breakdown means you need to find somewhere new to live, leading to worries about money, and, if you need to move away, loneliness.
Risks factors for depression include:
- a family history of depression
- personality traits, such as being too self-critical
- seasonal patterns
- drinking too much alcohol or using drugs
- long-term illness or injury
- head injury
- loneliness
- changes in hormones (for example, pregnancy or menopause)
Sometimes, depression may be a symptom of another medical condition, such as generalised anxiety disorder (GAD), hoarding disorder, premenstrual syndrome (PMS), or bipolar disorder.
