I'm sorry that you've gone through the shock of people behaving like that towards you. Yes, I can relate somewhat. I was in total shock when it began to sink in what had happened to me. There is a book by Pete Walker but I've forgotten the title. ...I think it was called cptsd something which you might find helpful. I think what happens in situations like that can be a lot of denial. I hope you can get to see a counsellor to help process the thoughts and emotions around what's happened. What you wrote makes total sense and I think we do it for survival.
