If you feel like you might attempt suicide, or may have seriously harmed yourself, you need urgent medical help.
• call 999 for an ambulance
• go straight to A&E, if you can
• or call your local crisis team, 0800 0516 171 (24 hours)
If you can't do this by yourself, ask someone to help you.
Mental health emergencies are serious. You're not wasting anyone's time.
