Check out "Social Services" in the local yellow pages.
Charlotte Emergency Housing is 704-335-5488 - I don't know what their services are, or their eligibility requirements, but you can call them and find out.
Also check out your county services in the blue pages - they should have some emergency assistance programs, or be able to direct you to community organizations that can help
Best of luck - my mother went through this: got laid off, ate through her savings and had to get rent assistance, etc., and luckily got a job at the last minute before she would have had to give up the apartment and go live with family. I wish you all the best. Just remember it's only temporary.
