I hope things have improved for you, but if not, I have found some useful ways to begin basic human contact, which will make you more comfortable in social situations. I always look at the person I wish to talk to, find something about them that is worthy of comment, and then ask them a question about it. "Nice earrings, where did you get those?", if they are wearing them. If they look tired, "Man, what a day!". If they are wearing holiday themed clothing, "Wow, nice outfit! I wish I could get into the holiday spirit too!" Notice something about that person, see them as a fellow human being who gets tired, happy, depressed and hopeful just like you, and make a comment that encourages them to talk about themselves. The magic happens every time, from cashiers at the store to people in line for the movie, to any other situation where you are around other people. SEE them, relate to them, and encourage them to talk about themselves. If they are good people, they will respond positively. If not, screw them, who needs to connect with assholes on a personal level?
