Hi, I read your other post, and I don't know if I can give you any valuable info, but I'll tell you about what I went through, maybe there's something there you can use.
My ex husband kept trying to kill himself, and we ended up in the hospital several times, (He did).
He was prescribed medication, which would work for a while, then it wouldn't so we had to swich again.
To make this story short, you wanted to know what to do when she gets back from the hospital.
First of all, they should not release her until she has gotten better on the medication and looks more stable.
Be aware that she can fool the doctors by spitting out pills that were given to her, thinking they won't help her. Until the medication starts working, you need to watch over her, like it's being done for her now.
When I got home from the trip to the hospitals, I had to hold onto all the medication, hide it. And only give to my ex what was prescribed at the time it was prescribed. I also hid anything sharp or rope-like around the house.
There are only so many things you can hide.
The first trip to the hospital, his mom and I took him home, we were advised to have a large man around (my ex was big) that could hold him down in case he came back out of the depression and got enough strenght to try again.
Or got violent because he may be mad at the people who saved him.
It did not happen, we were lucky there. He came out of it O.K.
There is a lot more to this, but I am sorry you are going through this, if you have any questions, knowing what I went through, maybe I can offer some insight.
But you are doing the right thing, and she seems to be getting diagnosed and medicated now. So praying always helps, and maybe she can come out of this one. Has she been on medication long? Has she been on meds before?
Does she accept that she needs help and meds? That would be a good start.
Keep writing, O.K. I'll keep checking. Sorry it took a while, but your title did not tell much. But there are a lot of wonderful people here.
