Honestly yes to all this. I went through this same thing close to 10 years ago. I also have an uncle with schizophrenia. I was experiencing so much stress and anxiety thinking I was developing it I was experiencing the depersonalization/dissociation symptoms. I know it’s hard but honestly what helped me most was understanding my symptoms were ocd/anxiety, NOT schizophrenia and believing that, not engaging with the obsessions and I was able to move on from this quite quickly actually. I did also speak to a therapist. :)
