I’m very sorry to read this. I had similar situation but not so far stretched Loan position.

Many years ago I made up my mind with doing so-called “system reset”. Wind down and start over

I think best way is to sell your business to competitor and reassign debt to new owner. At least this way you may end up with positive cash balance and no debt to start over again

But man. Sending you hugs of emotional support. Remember you are not alone in this world with such situation. People figure out how to solve this
