Help! I keep failing

I have exams going on, so I spend most of my days at home, preparing. Naturally, I do get stressed about exams, especially a day or 2 before. I was on a 6 day streak, when before my 2nd last exam I PMO'd. I think it was a way to release stress. Then before my last exam I again PMO'd, ending a 2 days streak, and again today(exam tomorrow). What do I do? I exercised to remove my urges, yet after some time I felt the urges again, and eventually lost to them. I keep failing, what do I do?

 

@yukon, How long has it been since you started nofap? Have you discovered any new ways?
@ReyHercules , I have a gym set at home (barbell and dumbbell), and that's what I exercised with, yet lost to the urges. I can't go to the gym, becuase gym means full workout which would lead me to exhaustion (i won't be able to study).
