Loneliness. It wasn't something I'd given a lot of thought to until lately. It sucks. I'm not entertaining enough to keep anyone's attention. I'm not good enough to have any friends. It makes me feel like such a loser.
Don't think that way, you can't change anything by moping. You have all the freedom you need to do something spectacular. Pick up a guitar, learn to program computers, play a game, build a house.. find something you like and go for it, learn it, be an expert. There is nobody to tie you down or tell you what you can or can't do. The world is yours.
