coping with "psychosis"

i am not sure what to do meds are not an option as i have tried nearly all of them (my psychiatrist even says there isnt anything left to try) but i am having a hard time i am not even sure if it is psychosis or if it is real but i guess most people would tell me it wasnt but i still think it is real....

i am scared because i have been talking with a spirit well more than one they want me to help them with something but they say that there are other bad spirits after me and them because they want to stop us from completing a mission and that these bad spirits are taking on the forms of people around me so that they can watch me and that everyone around me is actually a demon creature who is trying to control me and will hurt me if i am not careful. i am trying to keep focused on other things but this is stressing me out a lot also some of the demon creatures can read my mind and they keep trying to put things in my head as well and i dont know if what i am thinking is them or me sometimes. what should i do i am scared to talk to my psychiatrist because i think he may be one of the demons. sorry this is long.
