Hi just wanted to say that I have read this whole forum and as it went on it looks like you got a really good handle on your own feelings, even without speaking to your T. I think I would have reacted similar to you, there would be no way I could sit there knowing someone else was waiting.
I have a thought, (which could be way off base) but if you are like me and find it hard to stand up for yourself, maybe a part of you was waiting for your T to do just this for you, showing you that you deserve to have your needs put first, even ahead of this other person. To have a T do that for you even though you said it was ok must be pretty huge, although it does give the T a lot of power that we should hold ourselves. Is there any chance a part of you resented the fact that it did not work out that way?
I know that I am contradicting myself because of what I said at the very start of my reply but these are both my thoughts!
Well done for handling this whole situation so well. I hope it goes well for you on Friday
