I want to quit so bad!

I’ve been trying to quit for the longest time, i’ve been putting blockers on certain cites and everything. But i always end up going back to watching it again. I even spent money on an OF subscription.. And i really want to quit but it’s also eating at me that if i quit i’ll have wasted my money. I really don’t know what to do anymore i want to reclaim my life because im sick of spending my free time looking at porn and also with the time i’m looking at porn interfering with my sleep and productivity i don’t know what to do guys.. Can someone help?
