So, should I make an effort to get back into gaming, or just let it be?
There's nothing wrong with putting the controller down for awhile. Hell, after the release of Fallout 3, I played it to DEATH. Then I just didn't play anything at all until New Vegas.
I personally would reccomend GOG.com. Planetscape torment, baldurs gate, these old RPGs really got me back into gaming, as that "90s" formula for creating videogames really just stood out. Get into another hobby, focus on other things.
Gaming will be right here waiting for you when you get back!
What is a grown up---a miserable little pile of secrets...honestly though if you can't take time out from "grown up" things and enjoy a little fantasy every now and then, you'll run yourself ragged and probably have a shorter lifespan.
Also this. NEVER stop playing for some arbitrary self imposed rule to "grow up." Live your life, and enjoy yourself.
