What does your dad say about this? There's no way she can make you get money that you don't have. Just simply don't keep it anywhere that she can get it. Crap, put it in an envelope and mail it to a friend or something, if that's what you have to do. Partly joking on that one. Are you really afraid she's going to physically harm you? Is there any way that you could make sure you're never alone with her? If it's gotten to the point where you're afraid she's going to hit you in the face for not giving her money for cigarettes, than, it's gotten to the point where you need to take it to another level.
