I have thought about your situation. Your alternatives are limited under your current circumstances.
One important point to keep in mind is that you MUST maintain the separation of finances between your corporation and your personal assets. If your corporation must declare bankruptcy or be liquidated, you don't want that event to "spill over" into your personal life (beyond the absence of a paycheck from the corporation).
You are likely going to have to reduce the asking price on your commercial building - monthly - until you find a buyer. This is a real life "Monopoly" situation in that you need income to live on, your corporation isn't providing it, and you may have to sell your personal real estate to have income to live on.
If the corporation situation is hopeless, you and your husband should consider working for someone else in a field where your knowledge and experience is of value. Of course this is frustrating after 38 years in business for yourself, but "You gotta do what you gotta do".
If the corporation itself can be sold, or if the assets can be liquidated in an orderly manner, there is another possible source of revenue. It could be that right now the assets of the corporation are worth more than the corporation itself as a going concern.
Suppose your commercial building sells. If you really are going to keep your corporate and personal assets separate, DON'T use your personal assets to keep the corporation operating at a loss. You will eventually lose both if the local economy doesn't improve.
I hope these thoughts provide some objective clarity for you.
