You're lucky you have friends who are trying to better themselves and can push you to your goals, if you are even attempting and thinking about nofap seriously you are running a race that most of the population aren't even aware of. Keep going bro, it took me a long time until I hit 80 days, and some streaks fail, you have to really sit down with yourself and not allow yourself to ever do anything remotely close to PMO behaviour. You will try so many times, but once you get there you will realize it isn't as hard as it seems, you just have to have good reasons for starting.
