Facing Medical Bills While Jobless

I am currently unemployed and actively looking for work. In the meantime, I do not have the funds to cover a medical bill that has been sent to me multiple times since last December. I tried to see if I could set up a payment plan for $5 a month (that's all I can afford)—but they can only accept a minimum of $25 a month. Basically, I can't even afford to set up a payment plan with them. I understand that $25 is doable for a lot of people, but that is an amount that I am NOT able to contribute every month. I do not have the funds. The call center agents have also stated the bill will end up in collections if a payment isn't made within 90 days since 12/20/2024. I applied for financial assistance, but the approval dates in the letter do not cover the lab work that was done on 4/22/2024. I'm posting on here as my last resort.

Also, if anybody has any advice or tips for those looking for remote work, please let me know. I live in the middle of nowhere without reliable transportation. This is my first time looking for work without a car.
