It's nearly the fifth day of fasting and I can barely stand to my feet and feel a numbness in my mouth. Before that, I was feeling great and very pompous about how easy it was but now i'm getting real cold feet. I also learned about refeeding syndrome which could potentially kill me and I have to spend 2-3 days consuming small amounts of liquid or bone broth to get back to base and I'm thinking I made a huge mistake as my OCD is now telling me that eating a piece of bread in my current state could fucking kill me.

What should I do?
