I'm not sure. I remember being depressed in High School.. but not enough to be treated. I remember wild times and my first obsessions and distractions that caused problems starting in college. But nothing I was treated for.. even though it cost me my pHd and I suddenly quit the Peace Corps and moved to California abandoning everything. If I look at the pattern of my life I feel it has been there from college on. But I wasn't diagnosed until this past summer.
