Why does my mother hate me?

It seems to me your mother is simply afraid that you're growing up. You're mother's little baby. She wants you to be excited and happy for her at all times and that's simply not how you are anymore. I know that, but she won't see it so easily. You need to be patient for her, and its hard that she takes out her stress on you, but only cus she loves you and you're the one she is willing to confide her feelings to. If you really want her to pass the love on and are unable to maintain this with her anymore, you should think about being pregnant as well. This would solve the problem of the perfect little baby child for her. After your sister left she had high expectations for you that were simply impractical. There is however also the chance that your sisters baby may solve the problem. That is if you're willing to wait the months for it to arrive. I'd say find a nice boy and write up a contract that gives him no responsibilities to the child and agree that its purely for your mother. This would be the best gift you could give her at this point to solve the problem.
