Doctors are too expensive and there are too many gaps in social safety nets that allow some people to access medical care who otherwise couldn't. Sometimes people who can access medical care have had bad experiences with doctors. I think most people who go to woo, life coach hell, and different medical traditions were driven there by terrible doctors or desperation.
And I was too. But I wasn't taken out of that hell by the lifestyle coaches, I was taken out of that hell when "good" (knowledgeable and empathetic and available) doctors, who do exist, brought their actual knowledge and experience to my problem. After about 20 excruciating years.
The point is, you don't know if you have a small cut or a fracture. While the bandaid can help the lesser problem, you're going to have a very bad time if you let people advise you to just put bandaids on your fracture.
I'm not saying people shouldn't apply at all general tips, but people need to realize that it should mandatorily come with "and go seek professional help if your suffering is increasing or if it is hard to bear, no matter how long it takes". It should be encouraged, because people who are suffering from various kinds of issues like depression or bpd are likely already not wanting to go due to both psychological factors (anhedonia, anxiety disorders about what they'll find or how their finances affect them, self-abandonment) AND the state of their lives.
High-functioning depression? well there can be a degree of delusion to operate well enough ("It's not that bad" until you flip out). Or not functioning at all? then your income is likely lower than if you were feeling well, thus the financial stress and lack of access to convenient solutions for medical support. And then you just read people saying how they went from couch to being a CEO because they wake up at 5 every day and drink lots of water.. well cool for you, but if you were lucky that it wasn't a fracture that doesn't change the lack of diagnosis of MY thing!
