How to quit this game...?

Honestly, I think I've been in your place before (but not as serious). It might not be the same, but I play games a lot as a distraction, to cope, and to vent. My problems are difficult and I dont always want to deal with them right away.

To truely quit a game, I think you should try and find something in real life to distract you from gaming at all. Something fun and engaging that you want to do in your spare time instead of gaming. What I'm trying to say is, find a good hobby irl, maybe one that doesn't require a lot of time and money, or none at all.

Also, this is easier said than done but try and let go of whatever goals you still have in the game (if any). Let the game take less priority more and more over time. Then, I guess try and enjoy life more if you can, or deal with whatever problems you're facing. This is just an alternative method if you dont want to delete your account for whatever reason. That's all I can say and good luck!

Some good advice here. If your therapy primarily addressed your playing, it might be worth looking into further help concerning why you feel the need to play so much. Addictions are rarely just that; usually something is driving them, and it's possible the game is acting as a form of escapism for underlying problems.

More immediately, I wouldn't really recommend going cold turkey. If you're spending an inordinate time playing each day, it's going to leave you with a large block of free time you're not used to that can feel daunting to deal with. Try and give yourself a limit to how much time you spend on it each day and stick to it, and as Aeilyi said, try to find something else to put your energy into - find a new (non-MMO) game, read books, have movie marathons, pick up a hobby, join some online communities - the last one is particularly important if the majority of your social life comes from FFXIV, since the sudden feeling of isolation can make the separation even more difficult. But outside support is vital when you're trying to kick a habit like this.

Personally, I'd consider trying a new game if you're struggling at the outset; it tricks your brain into thinking it's getting its "fix", and without the time-suck and achievement-chasing of MMOs they're far easier to disengage from. If you choose to cut down gradually, don't join open-ended activities like PF farms or Pagos - give yourself objectives like finishing roulette or capping tomes, then log. It's not easy, and it does require some determination, but it can be done.
