I wouldn't apologise for posting anything here on this forum Zander. Post 20 times a day if that helps you, seriously! This forum is meant for helping each other and whenever you feel like there's something to get off your chest I'd take the opportunity here. Express all that you feel and experience if you feel like it, simply writing about it already helps a lot.
I can only imagine the difficulties you're going through, but you're the one experiencing them. Would it be of any help to write more in depth about what a shit day feels like to you? I guess you've already had every piece of advice thrown at you throughout your journey here so I believe there's little more advice that I can offer you. What I can write is that you've gone now about 1,5 years without porn which is an amazing accomplishment. You've been battling this addiction whilst dealing with mental issues, family, depression and whatnot. You're an example of resilliance and I trust that life will get better soon for you, it has to right?
Keep going forward!
