You have. Keep your chin up. I didn't respond before, but you asked if you should spend your savings trying to save your business. Hell no.
Whatever you were doing before may not be worth it. There will be opportunities for entrepreneurs on the back side of this.. But if you bury yourself in personal debt saving a business that can't be saved... You won't get to participate.
Don't worry about your SBA loan. No chance in hell the SBA will come after personal assets of businesses that don't survive. The lawsuits would cost 100 times more than what they recover and all of Congress would lose their seats for letting it happen.
Shut the doors if you have to. Come back in a year or two or whenever your industry is ready. No bank will hold this default against you. Then you can start a new business when you feel the time is right. Next time you won't make all of the mistakes you probably did the first time around.
It's not your fault. It's not a problem you can fix. Don't fight a battle if you know you can't win... Make strategic retreat and come back and kick *** when you have rallied your forces.
