i worked as a financial aid officer for over 4.5 years so I know somewhat about this.
Yes, your students loans (stafford sub and unsub) die with you

So that is a good thing. Your family will not be responsible for them,unless you got alternative private loans where they co-signed.
I doubt at this point, especially if you already had all the fees, added costs rolled into the cosolidation that they can do anything about it.
I had a number of students who joined the peace corp after attending the university. The general consensus was.... this was their choice. Not trying to be rude, but when borrowing money you always need to think about how you are going to pay it back. it's water under the bridge now, you can't go back and change it. But really it comes down to that, my students wouuld get so upset that they had all this debt they didn't know how they were going to pay it back etc, yet they were more than willing to sign the loan papers without even reading the bottom line. That is one thing they shoudl have thought of before joining the peace corp.
One thing you might look into is if your job or county has a program where they contribute towards your student loans. A couple of my students worked in education and asked about "loan forgiveness program." they ahve to work for the place for 4 years etc but the employer will help towards they loans a set amount each year. That is always one avenue to look at. Another avenue, before getting hired, ask if they have a program like that or would be willing to contribute toward the loans as part of the salary/benefit negotiating time. It's been known to happen.
I feel for you I really do. I have a 40,000 student loan. As much as I don't believe in finance charges/interest you might consider lengthening your repayment time. I know you have up to 30 years now. which is ridiculous. Obviously you wouuld be paying more in interest versus but at least the payments would be smaller.
My students would get very frustrated with me because I would always discuss their loans etc with them. For my students that borrowed money for living I would say ..."Buying a $10 pizza now will more like a $30 pizza by time you pay back you loans in 20 years". Is the pizza worth 30?
Good luck.
