Too many games are feeling like "work" after playing a while

For me, there is a mental block that I cannot quite pin down. It is not just that games have changed, or that I am not a kid anymore. Instead, I almost feel like I have some type of ADHD or ongoing guilt that prevents me from getting deeply focused on an individual game any more. And it is not just an issue of free time - I have had a lot more free time lately, but it has not really improved the situation.

I feel this kind of constant edginess as an adult (but that does not necessarily come from being an adult - it feels more like a mental issue rather than just being a byproduct of being an adult). It prevents me from just getting absorbed in a game for hours on end, day after day, in a way that never used to be a problem.

It’s like there is a constant voice in my head saying, “You can’t just sit here like this,” even when, frankly, I could because I have the time. It almost feels like adult self is constantly berating me with it being a waste of time (even though rational self can say, “Fuck off, I’ll do what I want”).
