I know I'm slipping into psychosis and the hospital I'm in won't do anything?

I'm at that stage of paranoia where I am still self aware I am still also aware I hearing things and seeings things that aren't there I have been off my antipsychotic for five days because it was reacting with my antidepressant and my lithium I was taking the lithium for biplar 1 which I wouldn't be surprise if I end up manic or hyper manic then thrown in a depressive episode or mixed episode I may already be in a mixed episode as one minute I'm depressed suicidal thoughts but with tuns of energy but happy and and laughing non stop at something I see or hear but the hospital I'm in the psych department think I just have cPTSD the reason I'm in hospital is I had to have a had op due to a dissociated episode where self harm happened by an alternate personality and he sliced through several hand and wrist tendons what should I do
