Hope, I felt exactly the same way as you when I got out. While in the hospital, the worst I had to think about was getting the laundry room so I could wash my clothes. I didn't have to worry about anything else.
When I came home (and I didn't want to yet) I felt disoriented, like "What do I do now??"
If your hospital has a day or "partial program" I would do that... that's what I did. I went back during the day for a couple of weeks. It kinda eases you back into thinking for yourself.
Good luck and do what's best for you, ok?
