Hi Detia ~ Since a lot of your methods haven't worked, have you thought about the possibility of perhaps needing medication?
When I was in therapy, even tho we were working on all the strategies, etc., and I was making SOME progress, it wasn't enough and my therapist said I also needed medication in addition to therapy. He said I was clinically depressed, so he referred me back to my GP who put me on an antidepressant, and I went back to therapy. I made MUCH better progress once the antidepressant began working and felt SO much better.
But since I'm clinically depressed, I'll have to be on an A/D for the rest of my life. I tried going off the meds once -- and I ended up in the pits of hell.

So I'll NEVER do that again.
Just a thought tho. Perhaps medication would help you as it did/does me. I know that no one wants to be on medication, but it's been a life saver for me.
Best of luck and God bless. Hugs, Lee
