Is it normal to be broke and not care?

I have owned a business for the past 19 years. I'd make a little money, but mostly I've lost money. I currently carry $190k+ in debt. About 80% of that was accumulated in two very bad years. Some of that could be retired by liquidating the business or selling assets, like my house, that is held in collateral. I've burned through savings, borrowed money from family members, have $0 in retirement, etc.

I'm divorced. I don't date much due to the above situation, though friends are always trying to set me up, and those I do go out with like me, I just don't want to get involved with anyone until my financial situation improves.

I'm working hard (60 hrs/wk and am taking classes, too) and I am optimistic that this situation will work itself out, long term. I have made some significant changes in how I run my business, and am open to getting a full time job (great economy to do that), file for bankruptcy...many things I would never have considered before.

My point here is that I'm in a situation that would make many reach for a revolver and off themselves. However, I have never been happier in my life. I'd rate my happiness meter at 9 out of 10. I have a wonderful extended family who loves and supports me. I've got a great kid, and I love being a dad. I have many wonderful friends, traveled enough, have good health, have many passions and hobbies, a strong faith and relationship with God, and like myself a lot, and most others I meet seem to as well. I'm resilient, and see these challenges and problems as opportunities.

So, my very long point is, is it normal not to be miserable in a situation like mine? Should I be more miserable, just as motivation? Am I resilient and optimistic, or just in denial?
