Mental health

Argh. I'm in a supportive environment with friends, partner, etc. Why does it still feel like I don't belong? Why do I have to go away and walk around because I feel like the ceiling is crashing down on me and the walls are closing in? Why does it feel like the world is too small for me?

I guess I'll spend my life running and pushing, in search of that mythical place where I have the room to stand up - and my mind will accept it. I predict I'll never find it.
