Don't make your character too stereotypical. Not all people with social anxiety fit under one umbrella.

I have social anxiety and I avoid crowds if possible. That's what you can see when looking at me.

I'm terrified of "sticking out" and I won't hide, avoid eye contact and other "typical" behaviour when I'm forced to interact with people. Instead I have "meltdowns" when I'm alone again. Crying, panicking, vomiting and so on. I obsess over what has been said and done, and keep asking myself why I said or did this or that.

well I have had social anxiety since I was very young. I catch myself stuttering or messing up sentences or words sometimes. I usually keep more to myself and would usually sit in silence at lunch while everyone else was talking. I would only talk if directly spoken to. I sometimes played with my fingers or my nails.

hide under a chair in restuarant everytime she sees a manager.

also she wears a short skirt with no panties on, flashing people to grab attention. farting in public. acting like a monkey, and being a whore.
