The only time I ever had any treatment when in crisis was when I went into work and pretty much screamed at my boss I was going to commit suicide...

This was about 4 years ago, the year before I was diagnosed with bipolar. They had me call the employee assistance program and see a therapist. But she was kind of a "happy puppy rainbow" therapist, and was nice and all but not exactly what I needed.
I've never seen a crisis team although I've probably needed one multiple times.
