I understand that you're both skeptical, as you should be.
My theory now is that ADHD is tied to diet and environment.
So basically what happened was, my psyche was already vulnerable to anxiety and depression when it got coopted by my physical health issues. I struggled chronically to make an appointment to see a doctor for years, always letting work and family obligations take priority, which prolonged and exacerbated my suffering. This all happened while I was broke and out of work too. After years of being gaslit about my instincts, going all the way back to childhood. That's why I didn't listen to my intuition and just take care of myself. I still thought there was nothing wrong with me, so projected my false confidence onto the world by blaming it for my problems.
Please view the list I posted more as leads than evidence. Also you're right, none of what I posted really applied to me until I hit 40, except maybe the general health advice about drinking more water and eating better. I do worry about leading people astray in their own journeys.
>My theory now is that ADHD is tied to diet and environment.
I agree that it is, and it has shown to be linked to diet & environment. ADHD isn't strictly defined enough to be only diet & environment though. There's a whole bunch of ADHD symptoms that present as a result of an underlying health condition. Hypo/Hyperthyroid problems look like ADHD-PI and ADHD-H. Vitamin deficiency and environmental poisoning can create symptoms too.
But also some people have it regardless of those factors, so it's really a broad label at the moment which could do with a lot more refinement.
