I used to feel that way when my therapist would forget when she was supposed to see me. Once, after coming in for surely more than a year at the same time and day she didn't turn up, because she'd forgotten to write my name in and had put someone else in instead. I've realised now that she's a person who just doesn't see things that way. She told me recently that she saw my name and realised I was coming in that day and she felt happy about it. She just doesn't remember me in terms of what time and day she sees me, even thought I've seen her for months, and sometimes even years at the same time. It's hard when you feel like their forgetting that is something to do with you not being important enough, but I really don't think that's it at all. I actually think it's most likely because of the opposite of your therapist seeing you as a number. She doesn't consider you to be her Friday at noon, she probably thinks of you as a whole person, and the time she sees you is incidental...and like my therapist, she just doesn't remember things in that way. It's not because you're unimportant!
