Why do i feel this way?

Well i asked a girl out and she told me tht she didnt rlly lik "the whole aspect of relationships" and i wus just a "friend" and she wus interestd in anothr guy. I hav been rejectd more times than anyother person i know 10 times now and im only gunna b a sophmore next year. And only 1 girl has ever gone out with me. I have delt with rejection before but y does this ome hurt the most?
