Nothing is wrong. I sent an email an hour after my therapy, received no reply, don't know I have the right address, but I've convinced myself that it's the worst possible outcome; that I've immediately broken some unwritten rule, and I've insulted and alienated my T before I really began.

I'm expecting to be chastised when I go on Mon. But have a sneaking suspicion that this is all just unfounded.

I am going to raise it if nothing is said.

However, for you, if the check is cashed and nothing is said then that sounds like tacit approval. I'd ask, after THAT cashing, was that okay? Just for reassurance. Has your T ever reassured you before?
