I know this sounds weird but have you ever done trauma therapy? Whether it was real or psychosis it was torcher. Even now you feel unsafe. Have you discussed what to do if the come back? how to address it? What matters is your quality of life and right now your quality of life is not good. Even if you don't have a psychiatrist can you get a therapist? The scary part is you have to be 100% honest with them.

X happened to me. I'm told it was psychosis but it feels real even now. I'm sorry you are dealing with this.
