How do I get my family to leave my house and leave me alone?

I have a very dysfunctional family. They are good people despite the fact they they are horribly dysfunctional. My entire family lived with me. I pay the majority if not ALL the bills. I have to pay for all the household items. If we have an outing I always have to pay for at least one other person. My mom, dad and sister stay with me. My other sister did at one point but she moved out because we kept arguing. I feel that they are all ungrateful and take advantage of me. Everytime I mention my option to one of them they threaten suicide. Every single member of my family threatens to kill themself when I mention an issue or try to enforce boundaries
