Okay! Update on the redo of the tank. She's on paper towels, nice and clean, got a new UTH, the thermostat is installed, I invested in thermometers for both the warm and cool sides of the tank, and I found a vet that treats Ball pythons in my area- I'm making an appointment and hopefully taking her in today or on Saturday.
Also, it turns out that my old UTH had badly malfunctioned. Really glad that I replaced it now. Yikes.
She's much happier now, and has perked up now that she's being kept at the right temperature and had a snack.
This is her current setup for her recovery, my next step (Besides the vet) is putting a backing on the back and sides of the tank so she has more privacy. That should be done later today!
Thank you guys for your help thus far, Basilisk will be a much happier noodle soon
