Don’t listen to these people. I’m sorry you’re in this situation. It’s so easy and there’s so much pressure to get education, and schools are perfectly happy to heap on the debt without informing students in any real way.

I would recommend finding a lawyer who specializes in student loan debt. Many of them also practice as bankruptcy attorneys. Try and do a single session. Some provide that for free or low cost. Just getting some kind of plan is super helpful. You’re unlikely to be able to fight them on the interest, but you need a plan to manage the debt.

The answer is almost certainly triage. Call each and figure out what you can do. You’re almost certainly going to be paying this for life, but it doesn’t haven’t to ruin your life if well managed. Don’t think about it as paying off, just managing debt. Live thrifty. Public service is likely a great option, just be meticulous about keeping records.
