Backdoor Confessions

I used be a tech guy in my friend circle.
So few of my friends who got hacked several times trusted me to install a backdoor for me to check their devices.
Most of them don't even know how backdoor works. And I completely respect their privacy so I didn't interfere in their personal content other than security issue. But one time I accidently clicked one of my female friends personal pics. Man there are more than 100 photos of her (posing almost nude)
I quickly stopped looking at those but I couldn't stop myself jerking on her.
From that day it become my addiction.She is in a relationship so am I. I know its morally wrong. How to stop this addiction? I feel so guilty day by day but I can't resist myself.
