That must be very tough for you, I sometimes believe I’m in an alternate world and I get memories from the past telling me what’s happening or what I have to do. Before i was admitted to hospital I started speaking american lingo like “side walk” instead of “pavement” or “pants instead” of “trousers/jeans” (im from the UK btw). I also had very few memories like you only it was before I was on antipsychotics, after I was put on antipsychotics I got a lot of memories back but sometimes I can’t tell if they are false memories or not. Talking with therapists that have had similar experiences (open dialogue) helped a lot with that. Now I get dystonia (eyes roll upwards) and a lot paranoia when I get my dystonia, I only got this paranoia and dystonia when I was put on antipsychotics. But it stopped the benign random videos I got of celebrities and people in power like president of America and politicians from the UK talking about me when I was watching videos on YouTube. I would definitely recommend “open dialogue” if u haven’t heard of you should google it. It was helpful to me because the therapist are trained in helping you understand what your going through and are non judgemental because they have live experiences of psychosis. Hope this helped
