You can work at your introversion. Introversion is about energy loss, you can develop a tolerance for interaction. It's like a muscle, the more you practice the more stamina you have. Horrific and all as it might sound, look for a local toastmasters club, go a couple of times, give some speeches. After a few months you'll be amazed at what you've achieved, and how much more easy it'll be to be a more social person. It just takes practice and effort.

Edit: I made that sound very straight forward, it isn't. But toastmasters clubs exist for you to practice interaction. It's very empowering. Go a few times, listen to others, start small, give a 1 minute speech, when you're comfortable, develop some more, talk a bit more. Force yourself to make progress, build that social muscle, gain stamina.
