Thankfully I was able to get home safely just driving it. I bought a few bottles of coolant before the drive, expecting it to all leak out, but I had almost no leakage, not even enough to add coolant.
As for the repair, since it's back home, my parents want me to take it to the mechanic. Which is fine; I'll have them check the rest of the system while they're in there, and probably have them replace the water pump as well.
Lastly, thank yall for all the advice and knowledge. It's good to know that if I need to make this repair in the future, it's something that I could actually do
