Can't recover

I train so hard and yet it has got me nowhere. I hurt and I don't even know if it is worth it. I run and run and can't stop. I want to, but I can't because what else do I have besides running? Nothing. Just work and school and that is nothing to look forward to, the only thing to look forward to in that is doing my art projects for my graphic design classes. School is not fun I am sick of being the quiet person. People don't believe me that I am shy, but I am and I never say anything in school, I just feel like I have nothing in common with my classmates. They have fun and I'll I do is workout, run, work, and do school stuff. They party go on trips and don't stress about stupid things. I stress and that is not fun, it makes life less enjoyable.
