Lotta good advice here man.
I've also gone through what you describe.
The high meat/high animal fats/low sugary carbs/low processed foods/no pharma diet, plus exercise/nature are the bedrock of health, including mental health. Our brains are especially dependent on proteins, fat, and electrolytes–take fish oil and magnesium supplements daily. Healthy eating/exercise also gives you something concrete to do, to get us out of the headspace that everything is relative to our feelings (shifting goal posts) and nothing is ever good enough (futility/despair). If you can point to simple, unambiguous actions as accomplishments, you can tell yourself you did work sufficient for the day, which creates a positive reward systems in the brain. We can't do it all, we only have to pull our own weight. The only reason it seems like it's not enough is we're carrying so many parasites on our back. Don't blame yourself for that, you still can only do so much, no shame there. All we have to do is hang on, have each others' backs, not give up, and do our part. Q team, POTUS, and the Mil will do the heavy lifting. You're not alone, we're not abandoned. The cavalry's coming.
Besides physical poisoning/starvation, the other system in which we're comp'd in this modern globo-homo hellscape is socially. Yes, the board provides some, but it's also work/heavy, and a bit disembodied from all the other physical cues we're designed to socially bond around. During the worst of the Hussein years, I found a lot of solace/encouragement listening to therightstuff.biz podcasts, especially the flagship TDS. They still have the basic philosophy we have here, so you feel at home instead of barraged with leftist lies, but there's a lot more silliness and humor, and hearing the familiar voices simulates IRL companionship/family/community in a way that the board just can't. Laughter has profound healing and protective powers. When we're in a funk, we need others to laugh around us–it's like yawning, it's contagious. Being able to laugh at problems provides needed psychic distance from the worst of their implications without lying about their true nature and causing cognitive dissonance. Whatever helps you laugh, do more of that. That's one of the biggests gifts the chans gave us: the gallows humor that's able to find and share joy even in the trenches. It's the magic in the memes.
