I have seen 3 therapists and a psychiatrist over the past year. Their goodbye styles varied wildly. Sometimes they would walk me to the door. Sometimes they would turn to their desk or phone.

I think it has nothing to do with you and everything to do with their mood or how busy they are that day. I'm not saying she shouldn't be consistent, I'm just saying it's her, not you.

Me, I just leave whatever they do. Sometimes without a goodbye, often without a thank you.
