A 2018 study by Mr. Cooper, a debt servicing company, found out that 68% of Americans are concerned about debt, 24% state it causes trouble with their spouse, and more than 33% are having trouble sleeping over credit card debt.
Interestingly enough, 8% of respondents would move to Antarctica for 2 years and 7% would donate a kidney.
The literature shows that many Americans don't even know the terms of their credit card debt and some don't plan on paying it off, ever.
Instead of flocking to every other cause of you not sleeping, look at some factors you can control, in which credit card debt is totally controllable.
If you are in this boat, check out Mr. Cooper, or another debt servicer, and figure out a plan. It's better than thinking of giving up a kidney.
