didnt read all the post just the first few but
inci be careful man i had a friend who went nuts i mean REAL nuts.
his parents bought him a guitar when he was about your age and he became obssesive bout it...
he practice about 11 h. a day and sometimes more (!!!)
his parents went abroad for two months when they got back they found him lying half dead on his bed fingers bleeding playing the guitar (it had very lil paint)... that two months he didn't go to school, (almost) didn't sleep, (almost) didn't eat...
they sent him to a hospital (you can guess what kind of a hospital) and now he is not allowed near anything that can make music...
