I failed

After 21 days without porn I broke down and I gave in. I was feeling tired, frustrated, confused, angry and horny. My blocked webpages didn't stop me, I found a new one, a better one. I enjoyed it so much and I felt so so miserable afterwards. I haven't masturbated ever since. I failed on June 20, I "started" with this goal again on June 21 so it has been only six days without porn. It feels so little, 21 days for nothing, I feel pretty depressed right now.
However, I can't give up. Ironically I'm posting here again because the urge is back. I hate so much this.
I'm definitely breaking up with F, and next time I'll make sure not to pick up girls randomly, I will make sure there is chemistry first.
Also, I'm making up new rules for me to avoid looking porn again.
