My therapist has canceled with as little as 30 min notice and I was ok with that because they were situations completely out of his control. As a result I wasn’t upset with him or anything, but I didn’t select “as long as I have not started the trek to the office, it is fine. Cancellations are not a big deal to me.”
The first part applies to me, but the sending part does not. Although I was ok with him cancelling, it was still a big deal to me inwardly because I was in a very rough place at the time and counting down to sessions.
