I think your therapist should have apologized for forgetting your appointment and I also think he should have given you your full 50 minutes, running late into the next person. Or at least 45, and then make up the lost time gradually through the day. It is not fair you bore the entire burden for his mistake and were the only client who got a shortened appointment. I hope he didn't charge you the full price.

I would bring it up with him next time, if you are able. I had a series of snafus with my therapist a while back--being double booked a couple times in a row, not returning phone call, etc. I did have a talk with him in which he explained he was overscheduled and overworked right now, and I asked him what he was going to do about it so these things didn't keep happening. It was a very professional discussion and he listed several steps he was going to take. I am hiring him for his services, so he is accountable to me. He responded well to this approach and did not act at all like "who is she to be questioning how I do things?" You are paying your therapist so you deserve to have this conversation with him. Then once the talk has happened, move on. No need to belabor it. Give him a chance to improve. Good luck!

BBF, I am glad you are posting here and will keep it up!
