>You've got a job, OP. Start small; say hi to people. You don't have to say much, so just start small and say hello to people you see every day at work.
OP here. I've actually been doing that. I'm able to talk to a lot of people there more than ever. It's great, but also kind of sucks. Without trying to sound egoistic, I'm a good looking guy so lately girls are eager to talk more, and likewise. However, after years of social isolation it's kind of hard to keep a conversation with any of them. I can have the usual lunch break chat about the usual things, but if I'm working with them the entire day I run out of anything to say and tend to stay quiet. I don't want to come off as a weirdo.
