I had success in that I'm still alive.
I have called a suicide hotline. They determined that I was a danger to myself. The police came to my house and took me to a crisis center where I was held against my will for seventy-two hours where other unsupervised, unmedicated residents of a facility for observation before being released.
If I am ever suicidal again I'll just skip the suicide hotline. They were no help, and those seventy-two hours were the worst of my life.
