Almost died from low blood sugar while ago

I came home from work and was so sleepy I took a nap. Had my alarm set for 12:20am to get up and take my medicine and take a bath before bed. Well that didn't happen. I woke up having seizures and convulsions from extremely low blood sugar! I had glucose tablets on my nightstand, but apparently in my seizures, I had knocked everything on the floor or into the trash. I couldn't walk and was covered in an ice cold sweat- my clothes were soaking wet. My glucose tablets from my nightstand were on the floor and I couldn't get to them but thankfully my purse was next to me in my bed and I ate almost the whole tube, then was able to hold onto the walls to make it to the refrigerator in the kitchen, where I ate a couple of spoonfuls of honey and drank some dragonfruit juice. Then I was able to walk good enough to take a bath and after awhile I checked my blood sugar because it still feels extremely low....but it's 478! Normally when it's high, I give insulin, but since it still feels low, I'm scared to. I don't understand what happened or why I slept through my alarm like that!
Super scary!! Times like this is the only time that I am scared to be single and alone in my bed. I almost died tonight but it's apparently not quite my time yet.
