I'm not sure

Hiya I'm new here I just wanted to get someone else's opinion.
I have a fear of going outside because I worry i will start sweating and everyone will stare at me and think there is someone wrong with me.. I get so worked up once outside i do sweat and constantly wiping my face and looking for somewhere to go to get away from people which attracts peoples attention.. Or i think everyone is thinking " look at that fat girl sweating" I'm not hugely over weight but i have very low self esteem. I only go out if i am with someone who can drive so i don't have to sit on buses in case i start feeling that same old panic that makes me sweat.. is this Agoraphobia? I have BPD and mixed anxiety disorder and OCD.. If anyone could shed some light on this i would be very grateful. Thanks for reading Rach

Thanks for all your help
