I thought life sucked and was on anti anxiety medications for year then realized I was simply allergic to half the food I was eating.
Your ancestors and my ancestors stuck around long enough to reproduce and raise their kids without offing themselves from depression, has something changed to make the environment less conducive to being a living human?
Obvious fallacy here: we are all descendants of those humans who survived - at least until having children. Those who offed themselves early are selected out of the genepool.
Note the above is not to suggest that there’s not a number of factors of a modern environment that we’re not properly/perfectly adapted for. But the handwavy “people weren’t depressed and anxious in the old days” is an illusion.
You'd be surprised what people can put up with cheerfully. A relative of mine turned out, around high school or so, to be allergic to wheat (which is in half the stuff you eat). It gave him regular diarrhea. He had grown up with it and simply assumed it was normal. How would he know otherwise? (A version of the 'typical mind fallacy' https://www.lesswrong.com/posts/baTWMegR42PAsH9qJ/generalizi... one might say.)
It's not as if people go around saying, 'good morning! I had my usual poop today, a good #3 on the Bristol stool scale, placing me within 1SD of the human norm! And yourself?' 'Likewise, likewise; good checking in with you and discussing our morning defecation, as is very normal for us human beings, ha ha.'
Start an elimination diet. Chicken and green vegetables are a good starting point.
I did chicken and sweet potatoes for a month. Had a ton of issues go away.
