I am not sure how much you have researched water fasting, but if you consume anything other than water - no lemon, lime, herbal or green tea, etc - you are not fasting correctly. And, if you EAT anything you have broken the fast, your body immediately changes gears and is out of ketosis and is in another non fasting mode. You must RE-SET to Day 1.
How you break the fast is also vitally important. Your body needs to be slowly introduced to foods staring with diluted fruit juice and then moving on to vegetable fruit drinks (fresh) and raw food which have the enzymes you need.

You broke your fast with shrimp and mayonnaise? And then you cninued from your counting in the twenties? Where to begin?

I hope you are doing well now but fear for your health if you take on such a fast without necessary research and or guidance which is abundantly available on the web.

Perhaps you did this just to lose weight. Most do it for many other reasons so adhere to the program. For me it is a way to re-order or shakeup my relationship with food and embark on a healthier way of eating so I am never again looking at 30 pounds overweight and feel better.

Wishing you good health nevertheless. fasting is not easy and takes tremendous discipline.
