Allow me to paraphrase a passage from the New Testament that I think speaks well to this thread.
Jesus and his disciples were walking together as they often did, and came to the city of Bethsaida. A man who had been blind since birth was brought to Jesus and they begged Him to heal him. Jesus gently led the man outside of the city prior to healing him. When they reached the outskirts of the city, His disciples asked him, "Master, what crime did this man or his parents commit that warranted him being blinded?"
Jesus' response was very telling; "Neither this man nor his parents did anything to earn this. This blindness is not for punishing this man, but for God's work to be revealed within him." And with that, He healed the man of his blindness. When the man was able to see for the first time in his life, Jesus asked him, "Do you believe in the Son of God?" The man's eager response was, "Tell me who He is so that I may follow Him." Jesus told him, "You have known Him, He has touched you and walked beside you."
I certainly will not try to tell anyone what to believe religiously or any other way. But my faith in God is the one thing that has gotten me this far, simply because there were so many points in my life where I felt like He was the only one in the world who loved me. If other people can see what my faith in God allowed me to survive and how He ultimately healed me when I was ready to be healed, then maybe they will also seek out Jesus and be healed spiritually, emotionally, or any other way. I've already seen it happen, I've already seen how sharing my walk with Christ has inspired other people to turn to Him and find peace with Him as well. That's just my take on how God plays into my suffering.
Happieness is something you must claim for yourself. No one is going to hand it to you. If your happieness is dependent on your circumstances, you'll never be happy. My life is infinitely better now than it was two years ago because of two things; God being in my life and my mother's life, and me healing from the inside out. It doesn't matter how healthy or unhealthy you are physically. Until you mend emotionally and spiritually, nothing your body does will matter. I've seen body builders and fitness models struggle with drug addiction and suicidality.
So to answer your question; no, God does not hate me. He doesn't hate you either. He and I are far closer because we've been through more together than many people. Just like the bond between soldiers on the battlefield who's lives depend on each other.
