Social anxiety.

I'm 15 and I'm homeschooled. I got home schooled for 9th grade and I'm homeschooled this year for 10th. I have social anxiety not to bad but bad enough. I really want to go to highschool and experience it. I feel like I'm missing out of so much that my friends that are in highschool get to do. So I was just curious if there is any tips to overcome social anxiety or anxiety in general. Thanks. (:
