When I get super anxious and panicky I notice EVERY TINY ANYTHING about my body. It sounds a lot like what you've described. I am so focused on finding weirdness that I find it everywhere. It's an awful feeling. I am so sorry. You're not alone in these feelings. When it happens to me it is 100% anxiety. (Although if someone were to say that to ME when I felt like that, I would still think I was the freak occurance where I am the one person who will die instead of it being anxiety. Lol) Hang in there.
