LITS - God does not hate you. Your mother abused you, and sold you into a religion that would continue to abuse you. She failed you. They failed you. Even Jesus is recorded to have said, "Jerusalem, Jerusalem, how I have longed to gather your children as a hen gathers its chicks under its wings... but you were not willing."
Neither was your mother, with you. Or the WTS. Or the world that ignores abused children, which in turn often leads to another generation of abused children, and so on and so on. (Not all of the world, of course.... some are saved, but too many slip through the cracks - even just one is too many.)
Now you're an adult and you're no longer a part of those organizations that fail children. You 'saw' them for what they are. You got out. How many people don't ever make it that far? God does not hate you, at all.
A bible study is one thing, but I would urge you not to turn your life over to another group of people, or even to the bible itself... as a final authority. Turn your life over to God and to His Son, instead, and cast your worries onto them. Trust them... in Spirit. And if you're not yet at that point in your life or faith, don't worry or get disheartened! Life is a journey and we don't reach the end of it all at once. Just trust that you one day will be at that point in your faith, and live your life for now, in love and with mercy.
