90 days challenge -- help me pls

Hello everyone,
I want to be at least 90 days without PMO. My problem is that I have anxiety and sexual dysfunctions that I want to solve and maybe stopping PMO will help me.
My biggest problem is fantasizing, and when I do it I consider like a relapse, so I give up and start M.
Can someone tell me if the fantasize thing go away after some time? I have also stopped using social media so much because it triggers me a lot to relapse.
Thank you for reading and good luck also for all of you that are fighting against this too!
(sorry for my english)

 

Thank you very much man. I hope it goes fast
