it sounds like you were really triggered by t. i dont blame you. is it possible for you to bring up how you are feeling at ur next session? i am sure that this has come up before for ur t, and it sounds like she is willing to work it out with you. i would tell you to relax, but i think it might help you to have t tell you directly, and that is why i am suggesting that you talk to her about it. i would hate for you to stress out about something that you dont have to. i think by talking to her about it, it will make the relationship between you closer, and also lessen the anxiety.

that being said, i think what the others have said about having ur mom give you money to pay ur t directly is a good idea. it would let her help you without giving her the reins, like you said urself. (sry i luv horses and horse metaphors haha).
