What can i do to stop my controlling and emotionally abusive family make me unhappy?

Emancipate: The fact that you asked says that if/when you are economically self-sufficient, cut the ties. Despite what they have told you, you are an adult and you are not responsible for their happiness. If you can pretend to love them, it may make things bearable for a time, but ultimately for your own sake, you will need to find some other community -- church, military, work, club. Be strong.
