$7K in debt, while certainly hefty, is really not unmanageable with the cooperation of your creditors.
It is VITAL that you contact your card issuers immediately. Explain your situation and ask for help in working out a payment plan. Then ask for it in writing, and STICK TO THE PLAN.
If the person you speak to is rude or belittles you, ask for a supervisor. Keep going up the chain of command until you get someone reasonable. (Truthfully, I've only ever had to do that once. When we had problems years ago, our creditors - except for one - were kind and helpful. We crawled out of a $10K hole in about 6 years.)
