Every state is different, but here are some things you might try...
Public assistance--food stamps and TANF--people are often too embarassed to ask, but we ALL pay taxes to support these programs, don't be afraid to use them!!
In my area, we can go to our township trustee for cash assistance. It usually isn't much, but every little bit helps.
Also try Salvation Army, United Way and look for an advocacy center in your area. There are agencies everywhere that help with the things you are talking about. It takes a few phone calls to get the ball rolling.
Call your landlord and the people you have bills with and see if they will work with you. There are usually agencies that will help with utilities--your utility company should be able to direct you. Getting help is often a full time job in itself, but help is out there... you just have to be willing to look for it.
Good Luck to You!!!
