This might help somebody but it's not super related to the article: in 2012 I had very bad and worsening depression and anxiety even though I had great, stress-free life. My doctor immediately suspected some deficiency in minerals/vitamins. We did a million tests and nothing out of the ordinary. Long story short, we did a sleep test and turns out I had horrible sleep because of my congested nose caused by sinusitis! Sleep is incredibly important.
