I commend you for continuing to push for a breakthrough! Am glad you came back and posted.

I can tell you're in your head a lot based on reading that last thread, something I struggled with a lot, and still do to an extent. It also sounds like you deal with some mania as well as anxiety, those uncontrollable racing thoughts, and that a recurring theme is feeling that you are better versed about theory and cross-discipline approaches that might work for you than most or all of the helping professionals you'd been in touch with.

I also got the sense you'd seen multiple helping professionals but was not sure if you had been engaged in long term therapy with any of them, or found any that were a good fit? If I'd read your post originally, I would have recommended you print it all out and give it to prospective therapists as a great, relatively comprehensive introduction to a key issue for you.

I wonder if you've considered Somatic Experiencing, or any other type of therapy where the therapist can help you integrate more mindfulness, more being in the moment, more grounding, more physical attunement into your process.

Also, have you considered medication or are you on any?
