If it wasn't the (probable) concussion I had that caused my schizoaffective, it was perhaps the stress of high school that started my symptoms. I put a lot of unnecessary stress on myself to perform, needing to get all A's, take honors and AP courses, get into a great college, etc. I was also sexually abused on a daily basis for some time before my first episode, but that was when I was 13/14 and my first episode wasn't until17 (though I struggled with anxiety).
