DBT I will be starting when the next one starts up. I have read that it's the 'gold standard' for BPD. I don't think I've had any past trauma, but i can walk down the street and see/hear things that make me feel like it's 1980 again or something briefly.. maybe my head is going through the same motions it did,same sequence of thoughts perhaps and it makes me feel like ive slipped through time.. its kinda weird and hard to explain.
