It Depends. Did you pay more than half of your living expenses and other support or was it your mom. You mentioned that your mom paid for insurance and phone bill while you paid for food and housing, so it all depends on who paid for more than half of the the living expenses and support. So if you paid for more then half of your expenses, then your mom cannot claim you.
