Can I get Food-stamps of my own when I move out of my insane mother's house?

I am a 20 year old woman in California and I currently live with my mom who gets Food Stamps for me. I am going to be moving in with my fiancee as soon as Fall semester starts for College because my mother and I don't get along. I was wondering if once I move out, will I be able to get Food-stamps for myself and what will happen to the Food-stamps my mother is now receiving for me? I am also worried that she will be angry with me once she is not receiving any financial support from me anymore. She gets enough money for disability for both her and my disabled sister, yet she is very careless with the way she spends the Food-stamps and her own money. She is in debt which is her fault but I just cannot live with her anymore even if that means she is going to have to suffer financially. I feel bad, but I have no choice, and I am bound to leave her anyways once I am married, have children and start my own career. She is just SO controlling and anytime I leave with my fiancee and spend the night at his place she throws a fit and tells me that I am ruining my reputation because the neighbors will think we are engaging in intercourse out of wedlock which is really none of her business and this is 2011, not 1911 but she is EXTREMELY religious and judgmental. She also has the potential to become very angry to the point where she becomes violent and a danger to others. She has in the past proven to be with me and others. She accuses me of being a whore, a lesbian, unfaithful, a satanist, mentally ill, and abusive which none of these accusations are at all true. She also performs unwanted "exorcisms" (Or so I'd like to call them) on me. I will be in the kitchen or anywhere and she will out of nowhere grab me by my arm and scream in my face for the devil to come out, and put praying oil on me. It is very scary and it disturbs me very much. I believe in God, and I am a Christian but I am not crazy religious like THAT. I'm getting sick of her constantly putting me down....I don't have the devil in me and I am a good person. I am never disrespectful to her even though she says I am but only because I don't let her control me and I visit my fiancee which I have the freedom to do. She has threatened to call the cops on him if she sees him around even though he has never done anything wrong to her. The only thing is because his step-mom and my mother got into an argument over the phone after he picked me up and took me to his place for Easter. My mother threatened to harm them if they did not bring me back so they agreed to take me back for their safety which I understand. But, my plans with my love and his family were ruined. She is not as aggressive anymore when I leave to go see him but she is unpredictable, especially because she is schizophrenic (literally) What do I do? Please help. :(
