It could that you have social anxiety if you're scared of interacting with people.
But if you just hate being around some people then it's not really social anxiety disorder.
There's some people that I do my best to avoid. For example I have one neighbor that if he's outside I always avoid him because he's a creep.
But I can be around other people and neighbors and talk to them when I want too and I don't have social anxiety disorder.
If you do hate being around anyone or have to wait until no one is around to leave your house then you most likely do have social anxiety disorder.
