Hi There, I Was Just Curious, Is There Such A

Hi there, I was just curious, is there such a thing as anxiety after the fact? As in, I'm nervous when meeting people or catching up but after coming home I have sudden panics that while I was out I've said something wrong or offended someone, I spend hours trying to work our what and why and make myself physically sick about it, even if I was completely fine and did nothing wrong. I am pretty socially awkward and don't make friends easily, I think this is part of the reason, or one has developed from the other over time
