As others have said, maybe it's just time to take an extended break and/or try a different game. Clearly you still like the game enough to want to play it more but by if you essentially just forcing yourself to play more than it is entertaining you then you're just going to lose the love that you do still have.

No game, regardless of how meaty it's patches are, is going to be able to legitimately keep a players busy and entertained full time and it's unfair to expect FF14 to be different in that regard. But it is your time and money and you should be spending your time and money on what makes you happy. If FF14 is not that thing right now then that's just the way it is.
