Yes, (aside from the hospital - big mistake btw. They just send you to the psychiatrist hospital, and say "Good luck.")
I told my brother, my best friend, and my psychiatrist that I was suicidal. They are trying their best to help me with the tools they have. My brother and I were never close (We're half brothers; he was never there for me me as a child), and telling him was one of the biggest regret I have. He does not deserve all of this. I could tell he didn't know how to handle the situation when he wanted to talk to my parents and my best friend. I told him that we have boundaries that he mustn't cross (telling my parents), and if he moves crosses, we're going to have a serious problem.
My best friend have been a lot helpful, although I can feel it is a bit difficult for her to relate to me. She lost a friend to suicide (before teenage age), and she is trying her very, I feel, to influence me on the right path. It's been going well so far, but I'm a bit of a manic, so everything is inconsistent. Hopefully she stays in my life, otherwise I'm afraid I'll go down the easy path, as I no longer have a support net.
