Starting to get urges after flatline or smthng like that

so yes till now my life was stressfree and nofap was like SPAM REMOVED (spam code #001) - REPORT TO MODERATION and stuff
now exams started, im new to this school so my syllabus is lagging behind, i sleep only 4 hrs a day and study a lot and stuff and this has given a lot of stress, and I wore these jeans and idk why but the inner part of thigh got ruptured and pains when i walk
Idk if this is because of the fat im gaining due to no exercise cuz exams and stuff but idk
I edged for 3 secs 2 days ago
i just fapped to see my shrinked boi (cold weather) grow and thankfully i stopped myself before it went from semi erect to eiffel tower mode.
I think this is because of all the stress im undergoing, exams gonna end in a couple of days. Hope i survive these couple of days because after these i'm gonna have a stressless life until the next exams.
