What an awful thing to have to cope with. I'm sorry not to have been able to post properly at the time, I've been away for a few days and couldn't get proper internet access.
Your reaction to the performance is totally understandable and while I can understand your wanting to hide it, and being embarrassed because you couldn't, I don't think you need be ashamed. It's sounds as if the trigger has led to a long lasting flashback or something, so please do look after yourself and take things as gently as you can. I hope that you can feel soothed soon.
