I lost hope in changing

It's not just the porn it's a few other things I have as goal but I just keep failing some people get so down cause they went a month then relapsed or even a week , I can't keep myself off it for three days it's like I put the effort the first two days then I come back to it cause I need something quick and intense it's honestly so tiring and it's making me so depressed but even worst it's making me feel like I'll never quit maybe I'm not tough enough or i don't want it bad enough
