Single mother in need of assistance with monthly bills

I am full time employed single mother and I need assistance with my monthly bills.  My 22 year old daughter is in her last semester of nursing school, she receives assistance for her college with her GI Bill, but the cost of traveling takes most of that.  Also, my grand daughter lives with me and she is expecting a baby in March.  My income is below poverty level and I never have enought to pay the necessities and buy groceries for  my family.  I have struggled for the last two months and it has finally caught up with me.  This month there is not going to be enough to pay everything nor have money for food.  Does anyone know where I can get assistance with paying my electricity and water bill?  Also need money for the extras it takes to run a house hold.  My needs are only temporary, until my daughter graduates and goes to work.  Since this is her last semester there are extra monies needed for her to be able to graduate and the fee she will have to pay  to take her state boards.  Right now I am - $17.00 in my checking acct. and will not get paid for another week.
