Had a school event today. One of the mums I talked to made me feel quite on edge, I only spoke to her and 2 others and other 2 I was fine with but every conversation I have with her I come out of it upset and going over everything I said! I can’t avoid her as our kids are friends. I only spoke to her for 10 mins but it’s literally been in my mind all day. How can I stop this? I’m not good mentally and I’m usually okay but things like this seem to trigger me and I don’t want to start avoiding school events. Please help!
