I suggest volunteering. I'm quite social but I run a charity and I've noticed a lot of volunteers that are generally shy or introverted become more relaxed and pick up social skills over time as most conversations and interactions with the group are centred around tasks. It's easier to talk and over time, you get more used to trying out new things. Might not work for you but I would definitely recommend that. Also, try that with a small charity rather than a large one.
