hungry

Im hungry and im at my moms house because she said she will take care of me until my due date i have about 10 days left and i cant cook or clean due to cramping back pain and just being overall tired. Im hungry. I ate at noon and now its 5 pm and im starving. Moms not home to cook and i called so saying im hungry can we go eat out and hes like we spent $300 on food this month we cant go eat again. I am so hungry nothing to eat that doesn't require cooking in the house and im not up for cooking. What should i do? 
No bread no cheese no fruits.
