Why Does It Seem Like God Hates Some and Favors Others?

Questions about whether the fact that some people go through intense difficulties and suffering indicates that God hates some and favors others, and whether someone is being abused because God doesn’t think she’s worshiping him enough. I constantly feel like God hates me because of a congenital defect that affects my career choices, my self-worth, and my bitterness towards God. Why does it seem like God hates some and favors others? If God lets Satan live to bring God glory and to test us, does that mean my friend is being abused by her mom’s boyfriend because God doesn’t think she’s worshiping him enough?
