CBT. But I never really thought about it, I just went to whatever therapist my psychiatrist recommended, and she happened to be CBT-qualified.
I did schema therapy for cPTSD previously, but unfortunately it made my mental health worse, because therapist wasn't neurodivergence-aware, and pushed me to do stuff that caused me autistic shutdowns (like socializing or exercising. We didn't know those were autistic shutdowns) until those accumulated into autistic burnout with executive dysfunction.
By the way, autistic and ADHD burnouts look very similar to depression, but are treated very differently, and unfortunately most psychs/therapists don't know that, and are unsuccessfully keep treating the wrong thing.
Why is it a bad deal? I understand roughly that subscriptions are terrible for your wallet and the less subscriptions you have the better. But streaming overall, it's hard for me to point to a specific issue. Not saying there isn't any.
