GOOD NEWS!!!
so on the calendar on the fridge where the MRI time was written I scratched it out and wrote (with an arrow pointing to what's scratched out) "waste of time, I'm not going." Immature, I know. But sometimes I'm bad at...talking. lol.

Just a few minutes ago my mom told me she's going to call the doctor and postpone and not reschedule it. Not just cancel it so the doctors won't get annoying about it.
I CAN FINALLY SLEEP!!!

Anyway, thanks to everyone who replied
