LOL... Not sure with all you've read about my art T if it taints this or not.
We can talk, make art or process art I have already done or have been working on. When I make art she asks what I am comfortable with her doing (watching, talking, making her own art, or sitting at her desk) The one time I made art with her I totally tuned her out which she noticed and commented on. She has explained art therapy to me as she was taught and the progression of the art and the media. I have a very hard time working on a project for just an hour and then packing it up and starting again another time so art making has been a challenge for us.
I have talked to her about three art projects that I had done and, for me, it was a comfortable way of bringing things up and processing them. Two of the projects were done specifically for awesome T before I started trying to work with art T. She was really good at walking through those with me, not making assumptions and helping me open up about them. all three are pretty intense. The third one was about where I was at with awesome T and it felt too vulnerable to share with him so I shared it with her first. Honestly those are the best sessions she and I have had. She commented that art was something I was able to use to really communicate what I was experiencing.
I also did art "therapy" in a day program and it was totally stupid. we made recycled paper and used a die cutting machine to cut out shapes and stuff to make cards. dumb. dumb. dumb. The woman in charge of it didn't have a clue and we never talked about anything. so... like everything else in therapy I think it comes down to finding the right T.
From what I have read of your posts I think it would be a really good option for you, especially if you found a T you could connect well with.
And, like velcro said feel free to ask questions. I can articulate things better with a question. I know things have not gone well between art T and I but I think it is just personality not the type of treatment.
