I can ditto Cafegrrrl's experience. The only advantage I saw in doing a partial hospitalization was that I got out of the house every day and got to eat a really nice lunch. There was one class on CBT that I really liked but it was only once a week because they didn't have anyone for that hour for those of us that weren't there for substance abuse.
One of the facilitators was studying for his degree in Pysch. I was in his group when I hit a crisis and he totally ignored me, the jerk! I hope he didn't get his degree, much less his license to practise! He missed a lot of what went on.
Other than that, it was okay. Got to make some really nice friends.
