There's plenty of (good) advice here on how to work on yourself to fit into a team environment. That's a very good idea. You may also want to consider that it is possible you're not meant to fit in quite like that. Being an introvert is a weakness if you want to fit in to an extroverted team environment, or a strength if you want to work remotely on self-directed projects. Introversion isn't worse than extroversion; it just means you recharge your batteries by being alone with your thoughts, and have to use your batteries to participate in group activities (the reverse is true for extroverts). Perhaps part of your frustration is trying to fit yourself, a square peg, into the round hole of a corporate team environment. I'm assuming you're looking for CS gigs, and that you have entrepreneurial aspirations. Maybe you should hit some freelance websites to fill your coffers & stay afloat, while working on an idea of your own on the side. If you're interested/open to travel, you can significantly reduce your overhead while still making decent wages by finding a place to work from that will lower your cost of living. I'm not saying this is the right way to go - I know nothing else about you - but it's worth considering that maybe the rest of the world is wrong, not you.
