I used to have delusions of grandeur and psychosis- not the same, but similar? I thought somehow the fate of a great amount of people or even the world rested on my doing the right actions.... But I couldn't figure out what they were? I also had a big problem with addiction. Those kinds of thoughts went away a month or couple months after I stopped all substances, I think? Unfortunately I had paranoid psychosis (ppl watching me, following me, talking about me, spying on me) for literally years. Best of luck. You don't have to tell me, but are you trying to quit substances at all? Or new in recovery?
