Ugh - been there, sweets.
Do what Frieda said - then take what you do know and get an even better yob!!! Better yet - use your time being unemployed to learn new skills ('swhat I did) - you may even be able to qualify for educational funds to take classes that will enhance your current skills. Don't get gloomy, whatever you do. Keep trying everything you can think of!
