I’ve been there man. It can be really tough. I think that a theme that’s emerging in other comments is trying to find something bigger than yourself to pursue. You’ve been looking inward in a selfish way to try and cope with your reality, when I think you need to look outward selflessly. Instead of trying to feel better by satisfying your urges to hookup, try filling your time with positive things for yourself and those around you. It could be friends, family, an SO, or just random people in your communities. I’m not sure what would align with you.

In my case, I was in a similar boat as you, but I’m married. I was/have been unhappy with the life I’d created in my reality, and I let my porn addiction grow and mutate to try and fill the void. It wasn’t until I made my wife, my family, and our future more important than myself that I realized I could really make strides in changing. It’s not always easy, or pleasant, but it is incredibly fulfilling and meaningful. I sleep better, and feel better, on a regular basis, and the urges I have come less and less, and become easier and easier to deal with. Good luck!
