I was fat at 17 and I wanted to lose weight. I water fasted down from 90kg to 74kg (35 lbs). I've had brain fog ever since (this was 4 years ago) and I feel stupider now than I did back then. Stuggle concentrating, especially when it comes to reading. I'm more impulsive, get angry quickly and often I just give up on solving a problem and get pissed and break a chair or something. Self control is gone basically. Also, my memory is really weak, I used to have great short and long term memory.

I figured the fasting might have something to do with it. Apparently you're not supposed to do that until you have developed completely (25) and it can affect brain development, just like smoking weed.

How do I get my brain back? I was never a genius back then but I feel like a total dumbass now...
