Haha, everyone's trolling you with "just uninstall bro"
"I need advise from fellow quitters"
Alright, here we go, so you do need to get another game to occupy your time. What I have learned though, is that if you try to replace WoW with another MMO, you will simply subconsciously compare every aspect of that game to WoW, and WoW did what it does very, very well. Pick up a completely different genre, something very time consuming.
I highly recommend Lego Star Wars, whichever one includes all 6 films in 1 game. It's probably $20 or so on Steam, and if possible, use an xbox controller synced to your PC. the levels are cute and fun, and require them to replayed in order to acquire every collectible.
After you either exhaust yourself or finish that game (give it at least a month or so), then switch to Far Cry 3, 4, or Primal. Same concept, they are hugely open and explorable, with thousands of items to collect and secrets to discover. I have gotten Far Cry 4 to almost 100%, I am missing 2 items (game says I think 99.8%).
After you spend 2-3 months with games that are
distracting, You'll have lost the urge to get back on WoW. For me, I always had the drive to get every class to max during 1 expansion. Although half-way done in Legion, I just couldn't stand questing the same zones any more.
Now my daily routine after work consists of watching Twitch on one monitor, and casually playing Overwatch or hearthstone, or of course LSW or FC 3, on my second monitor, and browsing social media. That's only if I don't have plans with friends or stuff to do outside of course.
It might also help you mentally to unsub, and then find something that costs you $15 a month or so, and put that money there instead, so that you will feel you cant resub to WoW unless you stop doing that other thing.
Call it ridiculous if you want, but I found that by subbing (paying $5/mo) to a few twitch streamers, I feel that my "WoW money" is already being used, and it feels good to support someone else's dream of being a streamer full-time, rather than feeling like another month of WoW sub goes to Blizz. Not that I dislike Blizz, I'm a huge fanboy, but Ive been playing WoW for 10 years now. 15*12*10 turns into a lot of money, and they've had enough from me!
Hope this helps! I feel like I was in the same exact spot as you a bit ago.
