Help keep our power on

My name is Liz. I am a mother of a 6 year old and wife of a disabled veteran. We've been on hard times for a few years, but always managed. We fell significantly behind on our power bill. This winter I managed to find a job and pay it down, but got laid off in April and now if we can't come up with $500 by the 18th of July (news we got yesterday) the power company will shut us off. Any money raised will still be used for the power bill, even if full amount is not raised.
