@c531994e When you're cold you shiver. When you run out of energy you can't shiver and then you become hypothermic. Low blood sugar, from not eating, also causes trembling. Get warm, get rest, eat something.
@68734993 I’m super warm now and trying to eat. Feeling better now. If anything, I have high blood sugar. But that probably dropped. Thank you for the advice!And the trembling and numbness went away. I might be on the road to recovery.
