I've got bipolar and have taken DBT. My emotions are huge, and the only way I survive them is my dozens of coping skills. I don't know how you're surviving. It sounds like barely! I agree with others - it sounds retraumatizing. I really hope your distress reduces soon, however it happens. Honestly, that intensity and what looks like little help from the therapist would be driving me to wondering if life like that would be worth living.
