I don't have diabetes, but I experienced a bad case of hypoglycemia.

It was the worst thing I've ever felt in my life. I woke up, went and brushed my teeth and started to get a massive rush and crash at the same time, my vision blurred, and I started to be unable to stand and nearly fell, I felt extremely weak, barely able to move my arms. I went downstairs and was hit with the warmest blast of heat I've ever felt. Like a hairdryer. I started Sweating so much, baisically dripping off me and looked in the mirror, I was nearly green. I looked dead. I felt dead. I nearly collapsed inside the kitchen but managed to sit myself down, and pour a glass of apple juice, and luckily it was near empty. I don't think I could have lifted a full one. All these symptoms just magically fixed by a sugary juice drink. It's crazy, and I get told I have too much sugar. Easily the worst experience I've ever had, worse than being hit by a bus, it was truly aweful. If that's what people go through commonly that have diabetes, I have to hand it to you, y'all are true warriors.

Tl:dr felt and looked dead, cured by applejuice.
