It wouldn’t surprise me if you get a lot of replies. It also wouldn’t surprise me if a lot of people were in your position.
On the actual debt … if you spent it on things that are worthwhile, remember the good that the necessary debt did. Was it a hospital bill that saved your life? Then remember that life is a gift. Plus, now that you are living you can solve this financial problem another day. Was the bill an education that made you more employable? Then remember that your mind is a gift – and God gives everyone some talent to develop. Your education will glorify God, improve yourself, and help your community. And so on.
But if it was a debt for frivolous things that didn’t last, such as fine living, vacation, etc. … well, live and learn. Jesus is very much willing to help us “go and sin no more.” While He may not always rescue us from the consequences of our choices, remember that our Lord was “tempted in all ways as we are, yet without sin.” I doubt they had credit cards back then, but they had money sins for sure. He resisted, and He will help you resist them too.
Regarding the emotions … are you sure it’s fear, rather than humiliation? (Not saying it can’t be both.) Fear makes it sound as if you’ve been exposed to “Prosperity Gospel” (prosperity theology) – and that group DOES consider it sin to be in distress. They believe you can tell someone’s Saved Status by looking at them. The comforters of Job seemed to have that problem. If memory serves, God wasn’t too happy about their attitudes toward Job’s suffering.
I’m not qualified to determine if your worry could be Scrupulosity. There is real help for that.
Otherwise, your worries also found a bit like the Ferengi in Star Trek. (In their religion, they really do go to a bad place if they die in debt. Fortunately there’s lots of money in their world. And in ours, too.)
I’m sure many blessed souls died in debt, and while distressing, it wasn’t the determining factor in either their life or their afterlife.
Debt is a real word. But with our God, it is not the last word.
So … two practical observations. One, if you can afford it, you might pick up a life insurance policy that would cover your debt if necessary. With that fallback position covered, you might feel a lot calmer.
And Two, pick up a copy of Dale Carnegie’s How to Stop Worrying and Start Living. (If you can’t afford it, get thee to the library.) It’s not as famous as his other books but it’s a lot better IMO. He gives very practical advice for problem-solving and it will lift a huge load off your shoulders to have a strategy.
