You don't have to do this alone
Support & crisis lines
If you're having thoughts of harming yourself, or things feel hopeless and permanent, please talk to a person. The lines below exist for exactly this — you don't have to be sure it's "bad enough" to use them. Reaching out is a strong move, not a weak one.
Canada
9-8-8 Suicide Crisis Helpline. Call or text 988, any time. Available across Canada, in English and French.
If someone is in immediate danger, call 911 or go to your nearest emergency department.
United States
988 Suicide & Crisis Lifeline. Call or text 988, any time.

Elsewhere
Most countries have a crisis line. Search for "suicide crisis line" plus your country, or contact your local emergency services. The international directory at findahelpline.com lists free, confidential lines by country.
A note on what to expect
We can't promise how any particular service will respond — policies and procedures vary by line and by region. What we can say is that these lines are staffed by people whose job is to listen and to help you through the next little while. You can call to talk, not only in an emergency.
If deliberately feeling a feeling has been making things worse rather than better, that's worth reading about too: when not to use this site.
A note on scope: some territory — schizophrenia, borderline personality disorder, and others like them — belongs entirely with professionals, and this site doesn't try to cover it. That's not a gap here. It's the edge of what a website should ever be.
