Thoughts of suicide and worsening of your depression or anxiety disorder

You may be more likely to think like this:
• If you have previously had thoughts about killing orharming yourself.

If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straightaway.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in yourbehaviour.
