I've lost over that amount in stocks before I learned to never invest in a company that is not making sales. It always takes longer than you think, and while you wait your investment declines in the form of dilution or debt. It's the same thing for your own startup. Do not take on debt unless you have a sale, and the debt is for fulfilling the order. On the brighter side, I eventually made the money back through my investments and you will do better next time. It seems in business there is no way to learn other than the hard way - I learned more about psychology than finance. Also, since you were extended credit, you probably are doing better financially than it sounds. That is, you have some asset backing the debt. So the greater challenge is forgiving yourself and moving on rather than the financials.
