Unfortunately, I am afraid nothing I say will make you stop. It really seems like you have to do it for yourself, on your own terms. I can only link you to
https://www.yourbrainonporn.com/ with the hope you read about the tangible effects porn has on your brain. If you decide to try and feel the need to stay in contact in order to keep your sanity, you can DM me and I'll do my best to support. My only words of advice are that you will notice changes after 3-4 weeks at least, hence "motivation" may be lacking and the attempts fail because you might not notice instant changes and get discouraged and shit. 3-4 weeks is a considerable amount of time when you're living day to day like me, but whatever. Sometimes, believing may bear more fruits and not believing.
