Life's purpose?

My advice to you, as I've been in your boat in the past, is to get up and get out there. The truth is, you might not have much motivation to do it now, but if you get up every day and shower and dress nicely, you'll feel better about yourself. Eventually, you will have the motivation to go out and socialize. It sounds like you are getting depressed. I would also advise speaking to a doc just to make sure there are no chemical inbalances. Good luck to you, and I hope you realize how great life can be!!
