I can't make it

I joined this website in the beginning of January this year. I told myself then, New Year New Me. I won't PMO anymore. (This includes porn, half naked models, women online in general) It's August 24th 2017 and yet I PMO 3 times today and my longest streak has only been 12 days? since then. Something like that. When I do PMO, I obviously trick my mind into doing it 2-3 more times that day because the day is already ruined. I tell myself I will restart every month but I always cave. I keep looking at half naked women. For some reason, my depression and anxiety continue to grow if I even take a few days off from PMO. Having bursitis and inflamed shoulder tendonitis for 2 and half years doesn't help (I have to rehab but am not disciplined enough) It's gotten to a point where I feel like posting this and that isn't a good thing. It's so tough, my addiction to porn, IG models, women in general. I continue to use them as my escape and not becoming the best version of myself. Please can someone give me guidance (even though I have been told before) how to get out of this once and for all.
