Yo, this Is my first post..........i've been boxing since i was in 6th grade now im in 10th, but i havnt been boxing in a class or anything, i box at home, and read books and watch tapes, i speedbag, jumprobe, heavybag the whole nine yards..........anyway for some reason, i get sooooooo scared soo frightned, (my hands and hair start to get sweaty, my heart beats like 1000times a minute) when someone wants to fight me, im 5'7 and i look pretty puff for my age, but it doesnt matter, if the guy is 5'2 and has no experiance in boxing, and i KNOW i can take him, for some reason i get MADDDD scared(the palms, the heart the sweat) i know for a fact im a good boxer cause i had people(trainers) c me box and tell me that im fast and powerful, I just dont understand.............why does it happen to me? is there anyway i can concer this problem that i have? is there anything i can take/or do to make this feeling to stop?

Thanks
