Any help/advice? Textbooks.

TLDR at bottom

Hi, I posted a while ago about not being approved for fafsa because I am a high school student (adult hs, don’t have a diploma yet) My classes told me a couple of days ago that I need text books. I can’t afford them though. Prior to adding the classes I was told as long as I had an estimated date of graduation that I would be fine for fafsa but it turns out that was a miscommunication on their part. So now im stuck. I have reached out to startrio, lgbtqia+, tbh and my professors directly but since im fully online communication is hit and miss by a few days, my appointments are a couple weeks out or they couldn’t help (or recommended what I’ve already done) I have checked every thrift store within a 2 hour driving range, every library equally and they simply just don’t exist.

TLDR; I guess all of that to say, is there an exchange community of some sort I could join to find a graduate who may have 2 text books I need laying around for cheap or to donate
