I am not old at all, but I have days like that as well. I get very frustrated because I'm lonely, and I don't know how to talk to other people. The only person in my family with Aspergers is my dad, and the rest of my family is oblivious to my problem because I function well enough to work and go to school. I would like to think that even when we become old, and feel like there isn't much left to live for there is still something out there we have yet to discover though. I hope you feel better soon.
