Why does life always get worse?

why is it that as soon as life starts going brilliantly it has to turn out going rubbish, I was so happy be for hand and now i actually feel like dieing and never going back to school ever again. My supposed best friend knew liked a guy but decided to set it up with him that they were going to prommtogetherr butnot reallyy just to make me upset ! i just broke up with a boyfriend that really loved me and nothing is going right. Its thatsort off time u will Prince charming would come along and rescue you. and no its not just teenagers being immature and wishing for things that dont come true.
