I think Wild Coyote makes a good point about being more attracted to people and also more attractive when you're manic. I felt at the time that I formed very close friendships while I was IP and we all exchanged email addresses. The staff and my psychiatrist strongly discouraged maintaining friendship on the outside however, because we were all pretty messed up and it was an unreal world where we all did things together and were experiencing the same things and seemed to have everything in common and it felt like no one else could really understand. I didn't keep up; when I adapted back to my real world I realized that we had very different lives.

I don't think it would hurt to get FB info and maybe email addresses. Just don't get your hopes up too high. Also, as someone else said, don't let all of this distract you from your own healing.
