It's your decision, but with a CH13, you will still have debt, just be paying back a portion of it, which is decided by certain factors, such as income and assets, as well as total liabilities. A CH7 is a total relief of all elligible debt, which is most consumer type loans, credit cards, etc. You can choose to keep some things, as things like cars, and homes have a certain exemption, depending on value. As example, you used to be able to have about $30,000 equity in a house.
One thing to bear in mind, is most lenders see a bankruptcy as a bankruptcy, regardless of whether it's a 7 or a 13. In other words, you will have bad credit either way, and you will be denied credit with no regard to whether it's a 13 or a 7.
If you really want out, then just do a 7, and be done with it. Your credit will be no worse or better either way.
Ideally, you want to avoid bankruptcy at all reasonable costs. For some people, due to circumstances, that is not an option. There are some people who just take the easy way out, no matter what the situation in life, but that's a different issue. You have some reasons, due to the health of your spouse, sounds like.
BTW, I had to to it back in 96 and today, I have great credit again.
Good luck.
