You can do it! I agree with the thought that the best thing you can do it actually DO something. If you find yourself becoming anxious, get up and go for a walk, go do something physical like exercise or something. And once you make friends, just getting up and going out with them is good! Tonight for example, I was feeling anxious, and instead of stewing in my anxiety, I texted a friend and ended up briefly going over to his place. Just the idea of changing scenery and getting your mind off something is sometimes enough to distract you away from your anxiety.. even momentarily.

Mindfulness and yoga have really helped me as well.

Hope that helps.
