i have the same exact problem..i played for the y when i was in H-Town then my dad and mother said i sucked so he said dont play but i still did...
i talked to them many times and sumtimes i told them the best parents r the parents that allows his kid to follow his dream...im an straight A student(well kinda) and yes studies do come first be4 anything else...tell them i can do 2 things at once like take a field in college and play bball in college ...my mother(not father) now believes in me more but her and my dad want me in medical still but she now supports me tho
talk it out and start planning wut ur gonna do/become with ur parents so they know
