Anxiety about being judged

I think mainly my anxiety is centered around a fear of being judged by my peers I'm not sure where it comes from or why but when I'm out in public I have an intense fear of people judging me. Not nessecarrily about my looks but just in general. I get so anxious and get extremely nauseous. Then it gets worse because I start worrying about getting sick in public and people freaking out. And I have such a phobia of pooping in public. Idk if it's just from being a girl and growing up thinking "girls don't poop" bla bla bla you have to pretend like you don't because it's gross and embarrassing and I know how dumb it sounds but it all comes back to the fear of being judged. It sounds outrageous as I type this and I've never really shared this with anyone other than my bf. I'm on medication for my anxiety but still have this fear of judgement.
