I feel bad for you that therapy gets you so wound up and upset -- must be awful to endure, no wonder you're questioning the merits of continuing.

I know from previous posts that you have seen/interviewed a lot of Ts, but is it possible you've just not found the right one for you? I'm fine with my T, but when I went for an assessment with a different T (on the NHS) I had a panic attack right there in her office -- even though she seemed like a perfectly nice person, and there was no 'reason', it was just beyond my control. Maybe it's not the same as your situation but I thought I'd share, just in cases

Take care.
