I really need help

I have been trying to quit for over 2 years now.

My main triggers are basically my phone. Its an android, Oppo brand, so it basically will not respond to any parental software apps and I have it in my room as I use it more than my computer because I don't like to use my computer to click on untrusted websites. Its also easier to turn my phone on as I need to start up my computer if I want to use it. I also have my phone in my room to set alarms.

So, how do I use my phone less if at all? If I eliminate that then I might have a fighting chance but otherwise I don't know what will help.

I should share that I am a convert to Catholicism and for the past two years it has been the norm for me to go to Confession for masturbation every week for the past two years. I have even literally fallen like three hours after coming home from Confession.

I have addicted for close to ten years. I started when I was 13 and I'm 22 almost 23 now.

Two weeks back I really felt God (sorry for those who aren't religious). I watched a video on Saint Philomena (I won't go into her story) but her story really hit me and then next morning (a Sunday) I felt amazing and I just wanted nothing more than to pray and I went for about twelve days without (that's one of the longest times for me) and I felt amazing. Unfortuanely on the twelth day I was hit by a huge urge and I fell. But now after falling, its like I'm in this ditch again. I want out but every time I try to quit I get images of the videos that I watched in my head just constantly and I eventually just can't take it anymore and I give in. I really need help. I can't do it on my own and I don't know how to make it stop. How do I quit?
