Introduction + Asking for Advice | 24year old male

Introduction
I'm a 24-year-old male, and I'm addicted to PMO since I was approximately 11 years old. I was always a bit shy and awkward when I was in my teenage years, and I developed a severe social anxiety at the age of 14 - 15. I used to PMO daily at least once or multiple times. Furthermore, I can't really say if it stands in connection with the abuse of PMO or if it just developed through some other reason. As a little kid I was always exploring things and ideas but since I'm a grown up I can't stop overthinking every step I make, which is extremely hindering especially while trying to build a business. Something that I also noticed is that I quit a lot of projects before seeing them come to fruition. I tried so many ideas for building a business but never really get anywhere because I stop too soon. But this wasn't the reason why I became aware of the NoFap. Something that I noticed since I got older is, that I'm getting more and more emotionally empty as I age. I don't feel many emotions anymore, everything feels so mellow in comparison to when I was younger. After a bit of reading, I came to the conclusion that in all my life, the only constant that always was by my side was the abuse of PMO. I also had an encounter with a beautiful woman, but the night didn't end well, as my P**** didn't want to fill with blood.
And I came to the conclusion that p*** might be the root of all my underlying problems, which plague me since I was a teenager.

Asking for Advice
The longest streak I was abstinent from p*** in all my life was 11 days and this was my first real try of quitting PMO cold turkey on hard mode. That 11 Day streak just ended yesterday because I started to fantasize about a girl I know, while I was laying in bed and one thing lead to another. (Which actually caused me to deinstall my porn blocker, but I have found a way to hinder myself from doing that again.)

The hardest part about quitting for me is the first day, because I'm an everyday user. After that the first week is actually kinda easy for me until I hit the Day 10 mark. Even if my consciousness is aware of the fact that I shouldn't watch p*** or m********, my subconscious is really trying to trick me to just take a little look at some spicy pictures or other things, and we all know how this ends.

Also, something that helped me tremendously in the first week was that I filled my day with different task's, so that I wasn't able to think about s*x much. And after I finished my days I was so tired that I just fall asleep in seconds.
(Which I think has led to me relapsing on Day 11, because I didn't have much to do on that Day.


My questions are:

Has anyone found a way to stop fantasizing about s*x, when they lay awake or daydream?

Is there anyway to get out of that horny state, when I don't seem to think clearly?


I hope I can find some good answers.
