Sorry it's been rough. I've felt embarrassed too, and I think that's an improvement over just complaining about work with my therapist, as if she was on the same plane as my neighbor. So, she knows me better and my weird sh#t. That's her job.
It sounds like you should definitely commit to yourself, if you really want to get better, and go to your appointment next week, even if your a$s falls off, or you feel scared or embarrassed. Just do it. Bring a stuffed animal if it helps. But just keep showing up no matter what and you will be able to work through this challenge you have going on right now. If you quit and eventually go somewhere else, you will find yourself likely in the same pattern, right? It sounds like you have a very patient therapist. She's giving you lots of chances, she's not giving up on you, but it's fair for her to ask you what you want from therapy and consider really committing to it...so that you go even when you don't want to or are afraid. I got through a couple phases of not wanting to go, or canceling last minute (and then rescheduling because I was a mess). A very little, young part of me also expected my therapist to give up on me. She wasn't going to...but if I had kept cancelling, there would have been a point where we just weren't going anywhere and she can't drag me along. She can only be there for me, 100%, when I show up...and a little bit in between.
The therapist's job is to accept all these parts of ourselves that don't seem to fit and help us integrate them or move beyond them. Our job is to show up. Would it help to post every time you want to cancel and have others remind you not to? Would it help to think of the positives, like you noted how your therapist could make you laugh and how she seems to help diffuse awkward situations? Try not to worry about her feelings or thoughts...or ask yourself where that is coming from and what your fears are, and discuss that with her.
There is something healing about going right back even after we share something that we felt embarrassed about or ashamed of. It's a recommitment to ourselves, but the therapist accepting us back helps subdue that whole pattern and all of those feelings of shame. Going back when you feel embarrassed or ashamed is a powerful step. I hope you can go next week and pat yourself on the back for the big move forward. :hug:
