Suddenly, I don't care.

I'm 44 and have been playing videogames since Nintendo/Mario Brothers came out. Up until about a month ago, I'd put 20-40hes/week into gaming. All kinds of games. I have 18k hours in War Thunder and played for almost a decade. No, suddenly...I don't care. I want to play, but the moment I start, I can't wait to stop. It's like the joy just died.

Has this ever happened to any of you? I've tried different types of games from my usually shooter/BR/racing games but the same underlying feeling of unrest and dissatisfaction remain.
