I messed up bad

I wanted a dopamine rush so bad yesterday, that even though I was doing so good with staying off my phone, focusing on work and just accomplishing my goals for the day, I ended up watching porn just because I wanted a rush and didn’t think it would cause any problems. Well I had a campfire with the youth group I am a leader for with my girlfriend and I ended up being a real jerk to her because I become a huge asshole when I watch porn. I ended up changing how I acted pretty quick according to her even though I dealt terrible the whole night but I’m thankful God changed how I was acting before it could get any worse. I’m literally hurting the ones I love because of this addiction, it’s not worth it guys, be free from this, I want to so bad I just want to be done with all this garbage.
