Ketamine treatment with Schizoaffective bipolar type?

hello! I wanted to ask this community if anyone has experience with ketamine treatment for trauma/cptsd but also have schizoaffective disorders? I also have OCD, but my therapist and psychiatrist are thinking about ketamine treatment along with EMDR, only thing is my psychiatrist is worried about my experience with psychosis. I’m currently medicated for that and haven’t experienced psychosis for about a year and a half now. Happy to hear from anyone who also just tried ketamine treatment, and their experience with it. appreciate it so much, thank you
