Why does god keep letting bad things happen to me?

Every time things start to go good in my life something always comes and screws it all up. I am so unlucky it's not even funny, my friends don't even want to hang out anymore because something always bad happens with me for no real reason. I see some kids with everything they could want and act like spoiled brats then me who tries his best to be humble and work my *** off yet I still continue to get **** on by the world. Everyone says life is a ***** well how come it's only a ***** to certain people. I'm starting to lose faith in God what should I do.
