I would suggest obtaining the following professional counsel;
1. A good accountant who can help you properly analyze your financial position.
2. An attorney who can provide the assistance needed for a bankruptcy IF that turns out to be what you need to do.
3. A credit counsellor who can help negotiate with the people you owe money to, if the lawyer cannot do so.
4. A real estate agent who can give you an idea of where you stand with your home's value versus what you owe on it and what your options are.
My best advice is to be proactive. You might be able to help yourself a bunch by negotiating with your mortgage lender to allow you make a short sale on the house. I think most creditors would rather work out some sort of arrangement, you may just have to pester them a bit.
I wish you the best. It's a really tough time that we are all in right now, lot's of people are in your shoes and lots more will be before it ends.
