I have this too but havent had therapy for it. Ive had cognetive behavioural therapy for my anxiety though. I hope you find something that helps.

I have agoraphobia. I dont like being in small rooms filled with people that freaks me out.

A slight bit but nothing debilitating. I get a little anxiety over it but it's mostly at a level of annoyance than panic. To a point anyway. I can't stand feeling trapped in a crowd when it gets too crowded.
