I feel like i am wasting my parents' money by going to boarding school.?

i am at a snowboard boarding school and it is 35,000 a year. i am way happier here that i am at home. i want to go here next year so i can graduate a year early. it is just so much money and i feel bad. My parents can afford it but i dont know how to get over the fact that there are a lot more talented riders out there and they would kill to be in my spot. i just feel like i dont deserve it sometimes. does anyone have any advice to keep me motivated and not upset myself like this? tell me what you think. be nice please im not too happy right now :(
