you can talk to us on here heaarrtt. You are definately not alone! Your sister obviously doesn't understand, is she anorexic perhaps, or maybe she has other problems making her be mean to you? If she is anorexic (or bulimic, or both), it's actually a kind of mental illness and she won't be rational towards you. Don't let any unkind things she might say get to you Whenever anyone is being unkind, it's because they are unhappy themselves, it's never about you.
