Change of mood, mindset, intelligence and sometimes even interests after relapse

I've been just curious if im crazy or if its a normal effect of fap.

I could say i am quite addicted to pornography as i can only keep my self off porn for about only 5 days. But i do not masturbate more than once a day.

In 2019 in easter i started believing in God a bit more as i thought there was a little connection between me and him.

I used to fap regularly quite frequently without giving any fucks about it until early in 2019 summer i started to feel guilty about it as i thought it was an opposition within me and God. (i am christian)

Until then i never really cared if i was addicted to pornography and i never really noticed if it had any impact on my life other than causing acne but rather i thought it was a positive thing. Though the real problems appeared in late summer of 2019.

Fap started having a different effect on me mentally. It didnt anymore feel like something that just caused me a little bit acne but something that impacted me in so many ways.

i started to notice IQ drops. For example there was a day it was like a month ago and i was doing nofap and it was my 5th day. We had online school and at the moment math for 3 hours that day. I was doing a really good job in class at that moment. when the teacher let us take a break i was really horny so i jacked off to some porn. I felt like my mood and intelligence had changed and i was right. After the break was over even my teacher noticed it. I was not mentally suited to do math at the moment.

I could tell so many stories about this but i dont want this thread to be too big.

In short fap affects my friendships, school performance, productivity, mood and worst my religious beliefs.

My question is has anybody had any similar experience?

Sorry for my bad english
