This is very interesting as my mum has schizophrenia, and her mum had schizophrenia and my grandmas dad also had schizophrenia, so as you can see, it heavily runs in my family.
When you say that you are told about the way you've acted and look back on it shamefully, is that because you are unaware when you are having psychotic episodes?
I can see when my mum is having an episode, it's very obvious, however it's very rare now, as it's very well controlled and she hasn't been in a unit for a very long time. But I always wondered if she knew what she was doing/saying, because to me she looks like a completely different person when it's happening. She has never really recalled things she said or did, but she can recall hallucinations/delusions, are you the same?
I feel like I am waiting for the day that it happens to me next, I'm 30 now, my mum's started when she was 27, and her mum's didn't start until she was in her 40's.
I do have anxiety though, and get paranoid very easily, I recognise this trait in my mum, she has paranoid schizophrenia.
