[Lore]

Social anxiety is loosely defined as being terrified in social situations. This means not being able to make eye contact, stumbling around a conversation (or trying to avoid one), experiencing physical pain or dangerous symptoms, and etc.

Social anxiety doesn't really fit at all with what you're describing.

I'd say your situation revolves more around the brazen (and idiotic) nature of those you choose to affiliate with. You've said nothing here that indicates you've done anything wrong, and all of your reactions seem more like typical responses to me. You're only human and shouldn't have to endure such cruelty for little to no reason.

It's not my place to say, but you also appear to be exhibiting self-doubt and blaming this all on yourself. This would be more attributed to depression, but if anything that was caused by the people around you. You should put a little more faith in yourself and listen to people who actually matter as opposed to those who know you have nobody else.
