I just recently did 11 days for suicidal intent.
my trip:

you're put on a schedule( wake up, breakfast, meds, group, day room, etc)

I felt time dragged if you weren't there with some cool people.

People with psychosis and schizophrenia freaked me the hell out at first, but eventually I learned to deal with them like other people.

If you are feeling like **** admit it, the longer you deny the longer you'll be there and the longer you won't get the help you need.

I was going to kill myself that day, not just thinking about it, that's why I went and it was a safe place to go.
