The elephant in the room is that the vast majority of people who are coping are supporting a family, usually with kids, or are at some age-appropriate stage on that track. The stupid crap and social hierarchies at work are trivialities, obstacles to be overcome and then forgotten. People raising families are often swimming in an ocean of oxytocin and existential fulfillment giving them huge mental and emotional boosts.

I'm pointing this out in case you're endlessly ruminating on what is wrong with you, why can't you just buckle down and deal, whatever, and you're coming home to an empty apartment and Netflix year after year. That's missing the big picture. I'm not saying you should start a family if you don't have one. Maybe you can't or won't, in which case, be gentle with yourself and make sure that you are taking the whole picture into account when you compare yourself with others.
