I have definitely experienced this from my biggest and longest psychotic break that happened around 8 years ago. I had SUCH a difficult time accepting that the incredible and so very real psychotic things happening to me and around me weren’t real. It’s still hard to believe now sometimes. I was 100% blind sighted. I don’t have such a hard time with any psychosis any more because I have come to accept that it is just part of my illness and I know what is. I have worked through the PTSD of that episode though it honestly took a very long time.
