Update. Grandma made it. My heart's acting funny, what with the two energy drinks I had (I also worked out cause my gym happened to be right next to the doctor's office, so that was convenient, but certainly didn't help the jitters and my heart).
I got to sleep at 7:58 and woke up at 8:03. I'm debating on whether or not to just stay awake as long as possible and try resetting my sleep schedule, seeing as I don't think a 7am-3pm sleep schedule is particularly healthy.
