I was once in a "behavioral health center" after a nervous breakdown.
It was a life-changer!
That's where I was diagnosed as bipolar for the first time, and was appropriately medicated. The nurses were great, the psychiatrist knew his stuff, and the technician was out of this world!
The technician was the one who conducted the group therapy sessions, which I enjoyed; she was also the one who insisted I draw a timeline of my life.
That was the most revealing thing of all!
It was not at all like One Flew Over the Cuckoo's Nest; nor were the patients creepy like the pictures you see of asylums in the 1800s.
Even the woman with severe schizophrenia was not creepy. She was a former schoolteacher and very kind. She just repeated several phrases all the time like a mantra.
