Just an update, the therapist is suggesting that I redirect my focus from what could be wrong to what is going on with me emotionally. That I'm avoiding fear over avoiding a certain outcome. I think this ties in with my idea that the effective treatment for this avoidance is to be prepared for what one would consider the worst outcome.
I may ask for a break in therapy because I think it's a mountain to climb and I don't feel I have the inner resources to do all this yet. Exhausting. But I think that's because of so much other stuff going on in my life right now.
