Alone in a room

How does one feel alone in a room filled with people... well let me tell you. It’s as if you’re in an insane asylum. Well that’s how it feels to me. Being around people that has no idea how close you are to the edge. You talk and laugh as if nothing is wrong but meanwhile your entire world is falling apart. Try talking to someone they said...I’ve tried but it was to no avail. I left feeling the same way I went in. That makes no sense to me, it really doesn’t. It’s hard explaining what’s wrong when you don’t even understand it yourself.
