Hey man, I see what you mean.
Even with people close to me sometimes it just feels like I'm not in the mood to be joking around (well not nearly as much as some others want to)..
It's an aspect of myself that I've always despised.
Just try and work around it and learn your limits.
"When I really explore the foundation of the world destroying machine, it's none other than the idea that we live in essentially a dead universe, devoid of any intelligence, subjectivity, or agency, that we must therefore project and impose our own meaning, design, and intelligence onto."
