Im with you. I am not diagnoised, (although I fit the diagnostic criteria, and will seek a DX when I turn 18)
and for example, monday, I was in an extremely agrivated mood, so pissed at everything and everyone, and one of my closest friends kept asking me "what's wrong" and I kept telling her "Honestly, nothing...thats the problem" and nothing was wrong...I was just pissed, course she didn't believe me.
Teehee since I said "thats the problem" she pulled my hair so I could have something thats wrong, and there wouldn't be a problem...

right now I'm OOBBERR hyyyperr!!
