You may be more likely to think like this if you:

are a young adult. Information from clinical trials has shown an increased risk of suicidal
behaviour in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
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 your behaviour.
