no one is trying to kill you for profit. They just don't care about you because you're can't make money for them. It's still bad, but different.
You meet a lot of skeptics because no matter how honest or correct you are, without access to a large test population and a way to precisely measure your dozens of tiny ideas that add up to a healthier overall life, it's impossible for an outside observer to distinguish you from quacks like Gwyneth Paltrow.
Also, being upfront about your suffering makes people uncomfortable and avoidant. Not your fault, but that's life.
You have a lot of disappointment with HN, largely because you see all these rich people who like talking to you but won't invest in you.
My advice: take a lesson from them. Put on a fake happy face, rewrite your narrative so that your pain is in your past, copy the obnoxious marketing techniques that smell foul but work.
You're in a "line" where everyone thinks you are bullshitting. If you can't beat it, join it. Run your effort the same way the dishonest snake oil salesmen do, and use your own conscience to tell you you are doing good. Make a little money selling whatever to health fad chasers, and put that money to good use as you see fit. Answer to no one but your conscience, but behaving in the way "polite society" demands, not because they are right, but because that's how you'll get paid attention and money.
