I feel like I can't physically or mentally relax. My body is always tensed up. My brain is always wired. I get lost in my head going down rabbit holes. Like, if I don't stand a certain way, then I'll look weak or less confident, and then I'll get treated poorly. So I'm constantly trying to readjust my body language. It drives me crazy. I wish I could just sit still and relax. I feel like I'm never in a comfortable position, I'm always tensed up and insecure about my body language and vibes I'm putting off. This causes a never-ending loop of anxiety, basically anxious about being anxious about being anxious. 

Any advice for what type of medication I may need? I'd really like a solution to this problem.
