Hi
I am sorry you lost your job! Have you tried the online free classifieds to advertise your services as there are so many of them. Someone here suggested to another person to become an aidpage distribtor and that is found at the top of the main page.
There are so many work from home jobs you can do, write articles, womenforhire.com has some work from home jobs listed and keep an eye out here as we have a lady who post work from home jobs.
Call 211 and ask about getting temporary cash assistance program for your state if your children are under 18. There are free medical and dental clinics see if this link helps you out

Below is my blog that has a lot of information in it and you can look through it to see if there is anything to help you here

In my blog there is a deal about getting gas money and let me know if you can't find it, you have to apply and wait to see if you get it.
Another option is wishuponahero.com and put in a request for gas money to go to your paypal if you have a paypal account which is easy to set up.
I hope that helps some and you can try microgiving.com as someone I told about the site was applying there but this person hasn't been back on line.
Good luck
Starshine
