More than simply feeling unhappy for a few days

An illustration depicting feeling down Many people go through times where their mood is low and feel sad or miserable about life for a few days. People with depression, however, experience these feelings for extended periods of time, i.e. weeks or months.

Depression is a genuine health condition that affects 1 in 4 of us over our lifetimes (Vivyan, 2015). It is not a sign of weakness or something you can simply "snap out of" by "pulling yourself together" (NHS, 2019a).

There are numerous different factors that make it more likely for someone to suffer from depression. These include genetics, upbringing or reactions to life events. Depression is often accompanied by other feelings such as anxiety, guilt and shame.

Thankfully, most people who suffer from depression end up making a full recovery, given the right treatment and support.

Types of depression

A depression diagnosis may be categorised as mild, moderate or severe depression. This categorisation is based on the impact of your symptoms on your life, as well as the type of treatment you're being offered. It is possible for people to move between mild, moderate and severe depression.

Additionally, there are also specific types of depression:

You should also talk to someone you trust. Let your friends and family know about your situation as they may be able to offer support and keep you safe from harm.
