If you feel like you or someone you know is in immediate/eminent danger, you should call 911 (or your country's local emergency line).  Explain that it is a psychiatric/medical emergency and ask for someone who is trained for these kinds of situations.

These hotlines also serve friends, family members and loved ones of someone who is experiencing a mental health crisis, domestic violence, abuse, addiction and many other issues. 

Even if someone at a crisis hotline cannot help you with your specific needs, they can point you to the right resources that can.  No one will ever make you feel bad for trying to get help, and no concern is too trivial or small.  If it feels hard for you to manage, it's worth reaching out.

Getting help for any kind of mental health or domestic issue can feel hard. Calling a hotline can be intimidating, and often it can feel tough to justify that what you're going through is "serious enough" to reach out.

The process has gotten easier though -- now there are many hotlines that let you text or chat with someone, without ever placing a call. Not only does that remove some of the intimidation of talking on the phone, it also means you can have a discrete conversation if you want or need to.
