Well, for lots of reasons. I've met and become friends with people who know and understand what I go through. I can get help and support and give help and support. I've been able to have "jobs" here, which has helped me to feel worthwhile and also helped me to have me a way to use a few skills. I had to give up my career, and PC has given me something to somewhat fill that void. I learn from other people here, too. I also enjoy the social groups, and the "fun" activities. I check here most every day.
