Feel like I can’t quit

This is a tough one but after 16 days i gave in like an idiot. What is crazy the 16 days i had no desire for porn and was feeling good not wanting to watch, and thought i would finally quit. Then just now wanted to give in and risk my streak thinking its fine. Now im beating myself up so bad cus what i just did. I find it crazy how going on a streak for a bit wanting no porn and started to feel confident as a person and in good spirt and having no anxiety in public, and bam just one night those dark thoughts come creeping in and won. I definitely hope I can learn from this cus it just seems like i keep making the same mistakes over and over and starting to think i can’t get this out of my life.
