For people actually doing achievs it's not impressive nor hard to get to 18000 on a long time main.
To the OP, get over yourself. Nobody gives a flying shit that your taking a break. I quit 8 months ago, heck I've even taken 4 breaks in total and not 1 time did I feel the need to draw attention to myself for taking said break.
That said, I hope you enjoy wathever your new hobby is and I wish you all a happy newyear!
