Feeling the same, even tho my life hasn't been nearly as stressful as yours. Games, especially new single player games with thousands of hours of content just aren't fun for me anymore, even tho I loved Skyrim, Fallout, Dragon Age and Witcher. But I still find a lot of fun playing games with friends.
Especially DayZ. It's like, really just taking a long walk with friends in the forest, because that's what the game is lol. Strolling arounds in Cherno, sitting together at the campfire and talking about our days, sometimes meeting with strangers and sharing that experience (or getting into a stressful firefight 😅). These are really the best experiences I had with gaming to this day.
