Please forgive me but I am not comprehending why you feel like you were being a jerk. Your brain was overwhelmed by an unexpected change. When you were with your mom, you probably went from ‘i am feeling emotionally safe’ to waking up from a nap and facing a threatening environment.
Well, yes, may be there could have been other avenues to channel your anxiety but.... just because you had an anxiety attack, it does not mean you were a jerk.
In my opinion, and you might disagree, there is absolutely nothing wrong with not wanting to be around people if you don’t feel comfortable. You do not owe anyone an explanation. You are not being a jerk, you are merely putting your boundaries to protect your mental health.
I too suffer from social anxiety and people drain my energy. So much that I would rather run a half marathon than be around people that I don’t feel safe with.
Everyday, i meet my daily quota while dealing with people at work.
Sorry for blabbing. In summary, I disagree. You weren’t being a jerk
