Parties make me extremely anxious

I guess it depends on the kind, but when it’s all people around my age (22), I get extremely anxious. I know I don’t have to go, but I have people who push me all the time to go to parties. I get to the point of hyperventilating almost and I have panic attacks... I’m anxious to even go to work every single day almost just because of socializing with people. That’s really all it is. I think it stems from being bullied and humiliated as a child because I don’t usually have the issue *as* much unless it has to do with my age group... does anyone else have this issue? I have a boyfriend but literally no friends other than that anymore. The ones I had turned out to be shitty people.
