I have a friend that I've known for awhile but I learned they have depression and anxiety. Whenever something bad happens they start drinking or talk about suicide. They have attempted it in the past. They were a romantic interest at one but I decided its better to be friends.

It happened again today where something bad occurred and she texted about sucidial ideation and other hopeless ruminations. I try to be there for her and help her through but it's such a tremendous burden on me. When one thing gets resolved I'm afraid of when the next thing will come how bad it will be and how long it will go on. 

It's tearing me apart. I know she is in such pain and I'm powerless to do anything about it. She has never had anyone in her corner fighting for her and I care for her deeply. I just don't have any control like so many other things I'm just powerless. She has started a new job and wants to see a therapist soon so she has made progress but how do I care for myself? Is that even a question? I get so upset and I should because when suicide is involved it's incredibly serious. I need help please.
