Hi Granit,
I'm so so sorry this happened! I think the thing about her not getting you til ten minutes late is very strange, as well as the radio being on in the office! I've never heard of a t doing that.
Everytime you write about your t something confuses me. I know you're not talking for most of the session but people communicate nonverbally. I don't understand why she just sat there in silence, and didn't comment on how you looked upset or saw that things were getting increasingly overwhelming and commented on your facial expression body language ETC. The question about spring also seemed really weird as a first thing to say especially when you looked so upset.
I agree it's time to move on. I know it's scary searching for someone new especially when you're very sensitive and struggle so much with even talking. My suggestion as I mentioned before is to find a t that is an expressive arts therapist. There it doesn't matter if you don't talk, you're expressing feelings through movement, writing, sandtray, art, ETC. These types of ts also seem at least from my experience to be extremely intuitive and sensitive to what people are saying without words. If you need help searching in your area I can help with that. Also, the group I started on creative arts therapy might be interesting for you if this is something you want to explore.
I just don't think another traditional t could help with this, as it would all be made about whether you talk or not. An expressive arts t wouldn't care about this, and would have a full apreciation for what people say without words. Please let us know how things are going. And I'm sorry this is so painful right now!
