My best friend tried to commit suicide last week. She is okay now and is getting treatment, and there is no permanent damage.

This whole situation has brought up a lot of my own darker thoughts that I've been suppressing for a while. I also, of course, feel very guilty and anxious about what I could have done but did not do. I feel like I should see my therapist and get help, but that makes it seem like I'm making this whole thing about me. I know self care is good and a need to take care of my own health before worrying about her, etc. etc., but one of my biggest fears is being a selfish or self-centred person- talking about myself when the focus should be on her and her recovery makes me that person. Shouldn't I just be able to watch a movie and take a bubble bath and be okay? I feel like such a failure of a friend.
