I need help

No matter what I tell myself, what approach I take, what mindset I put myself in, I always fail. I damn near am aware of every single way retention will benefit me and have wrote them down too but I still give in. I feel great when I first start and my life instantly improved but during the 5-7 day mark, the urges get so strong that I can not help but just visually look at porn, often leading to jacking off. The day those urges come in, I can hold them off for maybe another day or two, but like green goblins mask, it genuinely takes over me like an evil power. My mind gets all fucked up, that’s all i can think about, eventually giving in. No amount of website/app blocks or anything will stop me. I WILL find a way to get around them. My recent approach/mindset was to go on a full dopamine fast. I cut off all social media, stopped other habits like biting my nails as well, and obviously porn/masturbation. I felt so good-euphoric almost after i started this but then one bad day comes and the urges kick in so hard that i give in. The urges are bad like uncontrollable it’s so ridiculous. I also tried an approach where I only focus on getting through today and worry about tomorrow later along with visualizing the type of person I see myself being. I also tried filling my day up with other activities and trying to stay busy. But the second those urges kick in, it’s like thats all I can think of and I will find a moment to give in. The second I give in once, I spiral out of control. I also become emotionless and desensitized the second I give in. I know some people who do it once or twice a day and are still able to function properly and feel excitement towards things but I genuinely become near emotionless and trapped in a loop of lust till my wakeup call rings, I lock in for some time, and the cycle repeats. This is causing me not to progress in most aspects of my life either. I have been telling myself that I will fail a thousand times before I succeed but it doesn’t feel like I am making any progress, such as consistently increasing the gap between how often I give in. Maybe this is just a mental obstacle I am creating for myself but idk man. I don’t know what more I can tell myself. I genuinely feel so stuck. I need help.
