To sum up in a few sentences I've been struggling with things possibly related to schizophrenia for approx 15ish years, been diagnosed just treatment resistant depression, also saw a psychologist more recently and was told schizoid personality disorder. My mother had pretty severe paranoid schizophrenia and was institutionalized for a while, but in reading stuff online I came across the description of "simple schizophrenia" or "schizophrenia simplex" which isn't considered a diagnosis here in the US but is still in the EU, and based on the description here
it seems to match the best, especially about the slow decline.
I have never had any positive symptoms like my mother, but the negatives are pretty severe. Reason I don't think it's just severe resistant depression is that my mood isn't really affected, I don't feel sad, I don't feel guilt like described for depression, I just have extreme near total apathy, lack of motivation for anything, indifference to most anything, no pleasure in anything - things I enjoyed and loved 10 years ago I just have no response to, and just feel very dull, flat, and empty, I feel like my thoughts have become muted and indistinct, it's something that started in my early teens and slowly got worse over the years and at this point it's hard to even pull enough out of myself to care about that condition that I'm in and try to get better.
Anyone been given this diagnosis, or even just have mainly negative symptoms? Anyone who has actually improved those kinds of symptoms to any significant extent, medication or otherwise?
