It seems to me that majority of the people who lose interest in this game mainly only play this game. So it's pretty obvious that you would lose interest if this is the one and only game you are playing, or even just from a handful of games you are playing. Here is nothing wrong with taking time away from playing this game, or any other hobbies you may have.
Heck when I first started playing this game I stopped playing for a good year because I knew I would get burned out from it. Came back around season 3 and still enjoy it despite me playing at least once a day.
Just try something else. You make it seem like once you leave you can never come back to the game. It will still be here when you come back!
