Hi nichii, welcome to PC. You will have to get a licensed therapist to help you, preferably someone that specializes in dissociative disorders.
It wouldn't hurt to ask, but I'm sure that that's not going to happen. They got to run tests and talk therapy.
I use my psychiatrist for my bipolar and meds. Psychiatrist are medical doctors and they treat mental illness through chemical means. Psychologists deal with the inner workings of the human mind and have specialized training. About the only meds one would get is anti anxiety meds, I assume.
I hope things workout and get better for you!
