People like to sing the praises of CBT, but it is not the only therapy that produces results. My sense is that it is helpful for certain things but not so much for other things. I think doctors and insurance companies like it because it can be a quick fix for straightforward issues. Regardless of the validity of CBT, your T seems to be majorly missing the point. It's completely invalidating to ignore huge stressors and challenges while focusing on positive bits of minutia. That would absolutely make me feel worse.

A big part of my therapy has been learning to accept my feelings as valid, learning how to calm myself, and learning how to ask for help when I need it. On the way, it has made me more appreciative of the little things and less likely to get overwhelmed by my feelings, but I don't think actively ignoring the bad stuff would help one bit.
