When to see a doctor
If you have any signs or symptoms of a mental illness, see your primary care provider or a mental health professional. Most mental illnesses don’t improve on their own, and if untreated, a mental illness may get worse over time and cause serious problems.

If you have suicidal thoughts
Suicidal thoughts and behavior are common with some mental illnesses. If you think you may hurt yourself or attempt suicide, get help right away:

Call 911 or your local emergency number immediately.
Call your mental health specialist.
Call a suicide hotline number. In the U.S., call the National Suicide Prevention Lifeline at 1-800-273-TALK (1-800-273-8255) or use its webchat on suicidepreventionlifeline.***/chat.
Seek help from your primary care provider.
Reach out to a close friend or loved one.
Contact a minister, spiritual leader or someone else in your faith community.
Suicidal thinking doesn’t get better on its own — so get help.
