What do I do?

My boyfriend is extremely abusive and is constantly hitting, punching, and spits on me. He’s left several bruises and and marks on me. He even makes me starve myself saying I’m a fat pig if I eat one meal. Everyone is telling me to leave, I know should but I don’t know how. I’m not strong enough and I know I’ll end up coming back to him no matter what. I’m starting to believe I deserve this. I’ve even thought about killing myself just to get away from him. I don’t have any family for miles and I’m scared to get help..
