Guys help me analyze my true reason for relapse

I stuck to the no-peeking method for 30 days. My exams were mostly done, with just one left, I had five days to study in between. One morning, I’m not sure why, I got the urge to peek just once. during exam days, the urge came while I was traveling on the metro, but I managed to resist by repeating “no peek, no leak” in my mind. After my last exam, though, I woke up with an even stronger urge, and Instagram triggered it. I gave in to the thoughts and ended up peeking at some YouTube thumbnails in the music section on TV.

my analysis: bcz i got study vacation i did it coz last time also i did relapse when i refused to do a part time job after 5 days of doing it. or it could be i forgot to think no peak no leak multiple times that urge to do it strengthened. or it could be i entertained that thoughts.
