I believe the term you are looking for is : chronic depression, and not normal sadness. We have been given this beautiful gift of life, to be born and make something out of your short existence of this planet is what you should strive for.
Thousands and thousands of individuals have left their print on the history books, wouldn't you want to be part of that exclusive group of bigger than life human beings that decided to advance society in ways we can't even explain?
Life is precious man, you just have to grab it by the horns and give it your best every single FUCKING day! Simple as that man, killing yourself in my opinion is a cowardly act if you are not suffering from a terminal disease or locked to a bed unable to move your body.
Be the best you can be every day, I would love to still see you 6 years from now on on BHW posting about your success and how you turned your life around. You know you are starting to rub on me, your cynical and pessimistic posts, so I hope some of my grandiose optimistic attitude can fuel your ambitions and will to live a much longer life.
Eventually all those prints are going to vanish, be it through war or the heat death of the universe. There's no print you could make in history books that would last forever, unless you're literally Socrates or Augustus. Advancing society isn't really something I'd strive for, eventually people would either fall back to their old ways or use it for malicious purposes. Or it'd fire directly back at you, the same way democracy stabbed Socrates in his back.
Not just Socrates and Augustus. But to name some people more recent, Nietzsche & Jimi Hendrix. Now that's an absolutely random combination. But they're both being remembered the wrong way. Nietzsche's work has been altered to no end, and the people who love his work misintrepret anything he says, especially high school kids who are (for some reason) his major audience in this day and age. Then we've got Hendrix, whose fanbase (like the one of The Doors & Nirvana) consists of retards, people who make money off of their name although they've been dead for ages, or kids who wear their logos/faces on shirts but nothing else.
Look at Stan Lee. He died just yesterday, and already most of the people either moved on or you have the social justice movements who now bring out all the apparent racist and oppressing things he said since they didn't have the balls to do so when he was still around, not taking into account that the guy lived for 90+ years, and clearly in different times than the one we live in today.
There are some things you cannot forget, no matter if they were physical or emotional trauma. And frankly, ceasing to exist is the only definite way to get rid of them forever unless you manage to be drunk 24/7 or shoot up on something, which is both expensive and not the best option in the long run.
I appreciate your concern, however some people aren't meant to live long. I've experienced and seen both the poor & rich life, and have been unsatisfied with both. Losing certain people in my life, being betrayed in the worst way possible and 3 near death experiences through accidents are the main reason why I am the way I am. I've been on so many pills, have so many scars both mentally and physically... it's just not really worth it. People are tiring and the most selfish thing you can possibly experience in this world, so I wouldn't ever attempt to go on for someone else, especially when they're doomed to either die or betray you eventually.
