I don't think I've ever been totally right in the head, even though I wasn't officially diagnosed until my early 50s. I had night terrors from the time I was five or six years old, had my first major depression at age 10 and my second at 13. I think I had a few minor manic episodes thrown in there, but it got really bad in middle age and I finally got sent to a psychiatrist because my primary care doctor said I had something too serious for him to handle. I've been diagnosed for five years on the 7th of this month.
