If you want my best explanation for that feeling of hopelessness, it's mostly due to a shrinking ability to really feel like what you are doing is changing the
world in any meaningful way. This is in part comes from external factors such as automation, relative cultural gridlock (lack of production of new
creative ideas within the mainstream), and the enclosing relationships major
corporations are having with world governments. Another external factor
contributing to this shitty feeling is the rapid increase of our world population, and the increasing difficulty to make any significant impact on this massive cohort of humans. Internally, it may have to do with a lack of sense of what makes you happy in the long-term, versus short-term gratification. Self-gratification in accomplishing goals, helping make the world just slightly better, and improving oneself as a lifestyle, not just a phase, and staying disciplined at doing so will (guaranteed) improve your outlook on the world around you. Cut as many things out of your life that bring short-term happiness and instant gratification (masturbation, eating junk food, doing drugs, and video games) and drift towards things that bring long-term happiness like real life challenges such as purchasing property, starting a business that really provides people value, creating a work of art, anything you can think of that can't happen immediately, but will happen after hard work, patience, and self-discipline is put into motion. I swear anon, if you eventually find, or create you're place in this world whatever it may be, you'll be fulfilled to the point that no totalitarian, authoritarian, or tyrannical government will be able to take it from you. Just stay clean, focused, and strong, you'll make it.
I promise.
