I had a bad manic episode in January after being put on the wrong med by my GP. It wasn't really her fault, as I'd gone off all meds when I lost my job, even though I knew nothing good ever happens when I do that. I just couldn't afford them though and I had no insurance. So what was I supposed to do? I hoped it would be OK but it wasn't.
So when I got insurance again I went to my GP instead of a shrink, which was another mistake, and ended up in the hospital. My experience wasn't great or horrible, it was just what it was. Basically it was a place to be where I could be monitored while they got my meds right. I met some patients there who had really been through the mill and I admired their courage.
I guess another positive was that being there made me want to do whatever I had to do to never have to go back again. But it wasn't awful. A few stinky nurses, a few nice ones, lots of sick people. Some therapy groups that weren't that helpful, just something to do. Lots of food. (God, they fed us constantly it seemed.)
I hope you find what you need and get on a better track soon. I know how discouraging it is to be down and down and just not get better. Good luck!
