If you're feeling suicidal, go to your nearest A&E department as soon as possible.
If you're feeling very depressed, contact your GP, care co-ordinator or local mental health crisis team as soon as possible.
You could also call NHS 111 for an immediate assessment.

Bipolar disorder is fairly common, and 1 in every 100 people will be diagnosed with it at some point in their life.
Bipolar disorder can occur at any age, although it often develops between the ages of 15 and 19 and rarely develops after 40.
Men and women from all backgrounds are equally likely to develop bipolar disorder.
The pattern of mood swings in bipolar disorder varies widely. For example, some people only have a couple of bipolar episodes in their lifetime and are stable in between, while others have many episodes.
