What do I do from here?

In the past my psychiatrist diagnosed me with DID amnesia but I recently started seeing a new psychiatrist and he told me I had BPD. But can't rule out bi-polar completely.

I do have a lot of childhood trauma I don't really want to get into. So a trauma disorder is logical. I've done some research on it but not a whole lot.

I am currently being medicated for treatment resistant depression. Lexapro 20mgs and Seroquel 150mgs.

What steps do I take from here ?
