the mind of a [fill in the blank]

well, i dont know how to start, i really dont get how my mind works... it can go to hyper, to depressed, to concearned, then back to happy in a few minutes. it really ticks me off, and il be thinking while trying to think of something else, then get off track of both (its like a train running into another train). my mom once said that you were a genius of you could not keep track of your thoughts... but my dad once said that there is no noticible difference between a genius and a madman, just the motive... i wonder what side of the spectrum i fall under. i really get tired of people saying that i am a failure (sometimes they joke, and sometimes they arent), i mean it really takes a toll on my self worth, and i am also tired of people telling me that if i wanted to, i could do anything, that is just as bad. i dont know what to do anymore, should i follow the negative or the positive side, i have lost all bias... where am i, please tell me, just fill me in... throw me a friggen bone here!
