Social anxiety

So I have a bit of social anxiety. You could never guess it but when I have a conversation with someone who I hardly know my brain is overthink and analyzing everything I say the entire time and it drives me insane. Today I was talking to one of the other moms at the school. Both of our grade 3 boys were born premature. I also have a 2 month old now that was born term. Well I was telling her about how fast my labour was with her and how I couldn’t have any pain meds. Then she says “this was your first vaginal delivery wasn’t it, your son must have been born c-section since he was premature” well without thinking I agreed with her. My son wasn’t delivered by c section I’m not even sure why i agreed with her. And I didn’t even correct her. I feel like an idiot lol.
