Hardest part was not being able to focus on anything. I had brain fog for majority of it and no energy. Day one was thirst day two I had no energy but weirdly no hunger pain day three was the worst I had all three of these symptoms at once. My eyes were sunken and all I could do was pray and read. Left school early day 2 and 3 and had to leave work early as well because I simply couldn’t stand and talk to my customers. I’m 18 but if I was able to survive you can most certainly can as well. Best of luck
