Nothing changes until it changes. I know you're really upset at the moment but you need to take small steps to stand up to your parents. You are a grown woman and you can be strong. It's probably a waste of time to argue with them or try to change them. Just calmly do what YOU decide to do and what's best for you and ignore them. If you want to study then study. If you want to go out...go out. So what if your dad puts another piece of meat in your bowl? Just don't eat it. Once you start taking small steps the fear will fade away and it will become easier to take a stand on more serious issues.
