Muscle Spasms and Anxiety: Anyone Else Experienced This?

I didn't know it was anxiety related, honestly, I though my body had turned against me. I can feel the buildup in my joints, and tend to isolate myself before I get twitchy as often as possible. Sometimes it ends up with me writhing and crying in bed for nearly an hour before it slows down. Has anyone found a way to make it stop when it feels like it's about to happen? It's made life difficult to say the least.

Oh my God I thought I was the only one?!

Yes actually
