in response to Krissy7... Krissy,
Unfortunately, so many of us are in a similar boat. That doesn't help you, though, does it?
I find that it helps to call the places you've applied to 24 hrs after making the initial contact and then 48 and 72 hrs. In this economy, many places are looking for those people who demonstrate their eagerness for the job. I won't say it always works, but it doesn't hurt. I applied to Barnes and Noble and went in at least 3 times and called. It took a month, but they finally called for an interview. Don't be afraid to try McDonald's. They almost always hire even if they're not advertising for help.
You might try places like Salvation Army, United Way, local advocacy centers, and churches. You might also consider finding a homeless shelter that will take you in if you should find yourself in the worst case scenario... you have to have an address to receive public assistance.
IS there anyone you can ask to make even one car payment for you? It would put you in a better position to negotiate with the lender and they might be more willing to extend some leniency. My husband and I have lost 3 cars in the last 4 years. It can be difficult to swallow. Try to keep your car out of sight--in the garage or at a friends or something. Eventually, you may not have a choice, though.
Have you applied for unemployment? They also have a jobsite you can post your resume on as well as jobs that are posted. These are not always listed on other jobsite pages.
Spend some time making calls and finding out what services are available in your area. There are agencies that will help with rent and utilities. Also, see if your township trustee offers any assistance. Agencies are hard up for funds right now, too, so you may have to go to more than one place to get what you need. Don't be afraid to use food pantries for food, it will make your food stamps last longer. Often, food pantries offer personal care needs, too--things like deoderant and shampoo, etc. Have you applied for/ do you qualify for TANF?
I hope these suggestions will offer some help to you. I wish you all the best.... keep your chin up and keep pluggin' away.
