OP - While my debt isn't at your level, it's tripled since I borrowed it 30 years ago. So I know that song. What I did was consolidate all my federal loans. Then went on the federal RePaye plan, which calculates your payments as a percentage of your adjusted gross income as shown on your 1040 form. As I am now on social security and a pension, and as SS was not taxable income in the USA while I was in the UK, my AGI was only on my pension. The RePaye calculation looks at the federal poverty level, and any AGI that you have that is above 150% of the poverty level is what is used in calculating your payments. If you have graduate loan debt, it's wiped after 25 years of payments (if you're still alive) or is wiped completely if you die. I think it's 20 years for undergrad debt. Of course, you then owe the IRS the tax on the forgiven amount, unless you are technically insolvent at that time (the debt is more than your assets), in which case you can petition to have the IRS waive the tax on it.
You need to look carefully at which income-based plan you sign on for. Some will count your spouse's income. Some do not. I think RePaye looks at spousal income, but you'd want to verify that. You can change plans at any time during the year.
There has been no chance to be relieved of the debt through bankruptcy, but just very recently there have been court cases in California that the judge has found in favor of the debtor and allowed relief from private student loan debt based on repayments causing undue hardship. I am pretty sure the servicer was Navient in those cases and they will undoubtedly appeal, but it's a small glimmer of hope.
I got my debt by borrowing to pay for daycare and food, and went to second-rate state schools. In the long-run, in my field(s), aside from the connections made with fellow alums that were vital for later employment that I couldn't make at my insitutions, the quality of the education was about the same as if I'd gone to a private university. When my daughter was in high school her teachers were pushing her to go to expensive schools. We sent her to community college for two years. The courses there were literally identical to the ones at the local state universities, and the cost was ... actually it was free, given our income at that time. They actually paid her a bit to cover transportation. She then worked for a couple of years to get experience and save up some cash, applied to our local research uni, and was admitted on a free ride (same thing - our income was low enough that she was only expected to cover her housing expenses. As she was living at home, they were covered.) So the daughter got her BA with no student loan debt, and was able to do almost two years of ed abroad in there as well, for free.
Don't give up on dealing with the loans. Check the RePaye plan out. Right now there is a moratorium on loan payments - nothing is required to be paid until after 31 Dec. - that might help you a bit.
