Join a local improv group! I'm not particularly shy, but I'm a little stiff with my body in public. I started doing improv a couple of years ago. Really helped me open up physically in public. Most people in my group had some similar issues - either with public speaking or public body language. And if I'm honest, it's also a whole lot of fun. Most groups are very welcoming to newcomers. Check to see if there are any local groups offering introductory classes.
