I literally don’t know what to do and I’m so confused, could anyone offer advice?

I have 39k in federal student loans. None private. This is exactly what I had when i graduated 5 years ago.

I stupidly took out loans to get a bachelors and masters degree in humanities, and I have never made more than 2k a month. I was unemployed for 9 months, and I now have a job where I will be bringing home an estimated 1k a month. Together with my husband, we bring home 5k a month.

Under normal circumstances, my payment was supposed to be $400 a month. Thankfully, under the save plan and all the forbearance, I was able to chip away at it when I could, which wasn't often. I got it down i think to 37k. However, now that the save plan is over, its accruing interest and has now grown back to its original 39k.

I genuinely have no idea what to do. I never foresaw the possibility that I would basically never be able to find a decent-paying job. (I've applied to literal thousands of jobs in the past 3 years). I'm now working part-time in a kitchen (which I do very much like, but that's beside the point).

I am SO confused with all the repayment plans, and I'm worried about the interest exploding because I earn so little. I've read like 10 articles regarding the student loan plan, PAYE, IDR, RAP, etc., and I still don't know what to do, everything is so confusing and I don't want to make a mistake.

Does anyone have any advice at all?
