I feel Helpless, Help Me

These last few days have been rough on me. I've gone from being 80+ days clean to where I find myself now.... Bingeing and going back to porn every few days. I keep telling myself after every relapse "This is it, I'm done with porn" and there I am a couple days later right back at it. I feel down in the dumps. Everything was going so well in my relationship and now I just feel hopeless. Even though everything is good, I keep assuming the worst and running back to porn for comfort. I need help. How do I grab on to the need to feel loved by another human being without running back to porn? How do I avoid that demon on my shoulder telling me everything is going to fall apart because I've relapsed??
