I am very sorry to hear about your situation. In my life when I've found myself in over my head the best option is to cut your losses and move on. Looking a crisis head-on is the best way to deal with it in my opinion.

Evaluate your monthly expenses to review what you can reduce, rent for a bit while you get your business back up and running. Once things are stable begin to expand again.

My experience with being in over my head is to act like a trauma doc and stop the bleeding first.

Sending my best wishes.
