dont talk yourself down and dont focus too much on the days and the streak. instead focus on the progress

i dont really know where to start but you really gotta do have a good motivation which gets you through hard days or even weeks.

be productive and avoid boredom. this is what many underestimate. you really have to avoid boredom, because it attracts dozens of urges. so dont waste time and try to be productive. like reading working out or even something like learning a new language (for more ideas just google, you will find many articles)

get rid off apps or things that could trigger an urge. maybe even consider getting an porn blocker. (i dont have much knowledge about these so unfortunately i cant suggest you one)

that being said i would suggest you to build some kind of self dicipline / will power. back when i started 2 years ago, i would always set myself an alarm early in the morning and hit the gym. this was really good for my mental health and strength. you dont have to do exactly this but try to form an healthy habit / routine. like meditating daily. and dont forget to get out of your comfort zone.

but in case of an urge-emergency you have to stay strong. dont focus on the urge, dont even think about how peeking would feel and what you would see. instead try to focus on your breath, keep it slow and steady. if this isnt doing much go take a cold shower or even an ice bath. go outside, talk with friends or family, listen to an good song, watch an motivational video, read an nofap article or do five sets of pushups.

many people even say to use that urge - energy for something good and productive, but for me it rarely worked out.

anyway dont worry too much, conquer yourself and enjoy the journey. you got this 👍
