at 15 - 17 certanly showed signs, having lots of friends to having no friends at all on and off in highschool. I just assumed it was everyone else, no one wanted to be friends. Then oh these people are cool. No it was probably just me. depressive thoughts to aggressive, energetic behavior. Wanting all the attention and getting it doing stupid things.

But it got really bad where I could feel something happening with my mood and feelings at 18.
