Different state, but it happened to a friend. He was high and said something about being suicidal. Someone called 911. He was stripped and locked in a padded room overnight at the hospital. It was a very traumatizing experience as he had suicidal ideation but was not suicidal. Now that I think about it, the fact that he was high/drunk probably played into this - they had to wait for him to sober up.

I think your treatment could really vary. Are you getting any kind of help now? It would be so much better if you were seeing someone regularly, who got to know you, who you could call if you had to.
