Most likely, just something about it triggered you, or felt similar enough to something in your past experience that it brought up some of those same feelings. I would imagine that this would cause you a lot of distress, and I wish that I could make it better, but I don't think that anything I say will be enough. It sounds like this is bothering you enough that I think it warrants a call to your T to say that you are in a crisis and need to talk about it as soon as possible. If there isn't a T you can call, maybe you need to find someone you can trust and talk it out with them. You are welcome to PM me, or you can keep posting here.

Love and Support for You,
