relapsed today... feels super shitty

Hello everyone, I just want to vent on how I relapsed and share some benefits I felt and still feel during first few weeks of my reboot. I also would like some advice and guidance from more experienced fapstronauts out there.

I was ~20 days into no PMO.
I got super drunk yesterday, and I had a major hangover today. I lay on my bed for the whole day and I just felt so bored and lonely.

I started instagramming sexy photos and then I went to search other photos and eventually I wended watching P, then the M, then the O.

Feeling very guilty, shameful, and it feels like the last few weeks have been a waste of time and I feel like a failure.

The confidence and energy boost in the first 2 weeks felt amazing. My body language and posture improved. I am less fearful of the world and strangers (especially women). My penis got much bigger especially in its girth. My balls got bigger.

Biggest change I found that was different from most success stories was that I found myself becoming hornier everyday. I was super horny and I would get hard for no reason during random moments throughout the day. I was craving real life intimacy, and real life sex so much. I fantasized more and more and I dreamt of sex so much. I would fantasize every women that I see, literally every women.

I need some helpful advice in moving forward.

How have you guys and girls controlled your horniness and loneliness when alone?

I also want to know if there is any benefit to no PMO if I just keep relapsing every 2-3 weeks.

I crave real life sex so much atm, but I broke up with my gf 1 week ago and I am not really ready for a relationship nor do I know a lot of people to actually get into one or get casual intimacy/sex. How should I control my horniness?
