Getting help

Seek emergency help immediately if you are having suicidal thoughts, or thoughts of harming yourself or others.

You should also seek help right away if you:

  • Have trouble with alcohol or drug use, or have other mental health concerns

  • Think physical health symptoms such as experiencing injuries from over-exercising or excessive heartburn and/or stomach ache problems could be linked to your eating behaviours

  • Are experiencing prolonged trouble sleeping

  • Feel as though normal life stresses don’t explain your symptoms

  • Feel as though you have no control over your eating behaviours

Talk to someone you trust – a parent, family member, family physician or other health provider – about how you feel. They can help you determine if you need further help to deal with the issue. Medical help and counselling can help you recover from an eating disorder. Medical treatment must be prescribed and monitored by a physician, and recovery often involves a team approach with other mental health workers who may be available to help.
