While on one hand I completely agree. On the other hand most generations in human history saw difficult times. One thing we have now is easy access to extra layers of constant despair by always being able to see any bad thing that is happening every minute of every day, on the news, on social media, from our politicians, etc. Then it even creeps into discussions with friends. The general dispare has crept into the discussion and taken over. But at the end of the day, most people have food, shelter, water, family, friends, and some level of healthcare (all be it problematic in the US).
For those of us lucky enough to not be destitute, or a current or future target of a repressive regime, it is important to remember to take some time to actually enjoy life instead of always feeling helpless about a profoundly imperfect world. Depression caused by the status of the world can also be avoided by taking action. Those that help, rarely let the status of the world get them down. Because, they know they did their part to move it in the right direction.
I will grant that social media has given us access to all of the misery we want all of the time, and that those algorithms also prioritize content that makes us angry.
However, it would be toxic positivity to say that things are actually fine or even pretty good.
Things are objectively getting worse. Income inequality is somewhere between near gilded age levels and worse. The planet is dying in front of our eyes. Fascists are taking power in many governments.
Things are actually pretty bleak. That doesn't mean there's no hope. But burying your head in the sand and pretending things are fine ... well, I can understand that impulse. And I can understand that for some, it's a coping mechanism. And for sure, do what you gotta to get by and all. But it's not helpful in the broader sense.
I don't disagree with a single word you said. But having perspective and leaving time to be human is not burying your head in the sand.
The last things I tried to say was that taking action is one thing you can do to mitigate your sense of helplessness. People who help others or try to make the world a better place often end up in a better mental space. It has the added benefit of working against all of the bad shit that is happening. Pick something, anything you care about, and try to make a difference. Even if you only make a tiny difference, if a thousand other people go out there and make the same tiny difference, suddenly you've moved the needle. In my experience, despair is nearly always coupled with paralyzed inaction.
