Don't know what to do....

As much as I gripe about my husband, his income is quite literally the only income we currently have. Today he came home from his temp job and long story short he had been fired from it. They wanted 100% accuracy when picking orders and Mike had screwed up on two orders. Don't know what to do. Having nightmare scenarios where we wind up in homeless shelters or my car. (Granted if worst came to worst his sister or my parents would probably put us up.) I'm truely scared right now and feel helpless!
