I figured out some of the reasoning why I, and other people feel tired and screwed up quite a lot: abuse and completely insane expectations.
We have many impossible roles and responsibilities, and people abuse us when we inevitably can't meet them. This is other people shoving their problems onto us, or shoving more of their problems onto us than we deserve. To them, we're just machines to solve their problems, and even then they're abusing the machine....
Even if somebody's problem is ours to deal with, like at work, too much gets shoveled on us. Work quotas are difficult or impossible to meet, because they want to squeeze every last drop out of us, and sadly this often comes with screaming, threats, etc. This is the same as someone screaming at a machine and threatening it, except worse, because we're talking about a person here. It doesn't help solve problems; it creates them. Same thing goes with semi or totally voluntary measures. Relationships and friendships.
All of this leads to our bodies being out of whack. Depression, anxiety, ulcers, hair loss, migraines, stomach problems, weight gain or loss, etc. Stress was natures way to tell our bodies to STOP doing something. Except we can't stop doing a lot of these things, and so our internal systems get all out of whack because you need to compensate somehow, comfort food, alcohol, drugs, laying in bed (depression), etc.
Worse yet, if you don't seem stressed out enough, that leads people to think you're not trying....
Not sure what the answer is just yet, but identifying the problem is huge. Will have to think on this problem and how to solve it.
I made a nice tree:
