I'm also having trouble with not caring about what others think right now. But I guess my situation is a little different. Since breaking it off with my ex and friends who talk about us, I'm trying to block it all out. It hurts, and I just feel like I want to be alone, but at the same time I don't want my friends to think that I don't appreciate all that they've done to help me move on. They have helped, but sometimes I just don't want to care about other people for the time being and just wanna be with myself...and the loneliness kills, but at least I'll be alive and i'll be myself.
