Yeah, that's called anxiety. We all have it. If you're watching enough porn and PMOing enough to have brain fog, your brain is low on all the chemicals that naturally relax you.
Yeah, I recently got it. Really concerning but blood test was fine so... Do you feel really spaced out as well?
Sometimes, most the time it makes me feel really air-headed and spaced out, fatigued and in a monotonous mood or bad mood.
I almost fainted when I was working out. Because of withdrawal I started having problems with blood pressure when standing up. Now it has improved a bit.
