Absolutely man. Your words definitely ease some of the stress. I just dealt with something important yesterday and received some pretty good news, so yesterday and today have actually been 95% PAWS free for me!
I think you're right about the reduced blood circulation. My hair has thinned a lot ever since PAWS started (though my beard / eyelashes / eyebrows have remained the same?!) The exhausted look is absolutely an indicator I've noticed too actually. I never paid much attention to it, but now that you mention it, I recall during the bad times having heavy and shiny eyes (almost like I'm sleepy)
I definitely understand the internet triggering PAWS. When I was back in my prime PAWS days (like 5 months ago, lol) the internet and especially news would really exaggerate my PAWS. To be honest, they still kind of do now, but to a much, much lower degree. Going outside definitely helps.
I totally agree how easy it is to forget the crippling anxiety. I remember waking up almost every night with my heart racing, sometimes not even able to move my body or think a single thought due to anxiety. Waking up in the morning with my heart racing too. Going to bed with my heart racing too. Man, the anxiety really hit hard. I've actually forgotten about those times as the anxiety is diminishing to very minimal amounts for me. There are more and more things sneaking into my list of activities I can do without tripping into a PAWS wave. And the things you mentioned have definitely made it in there. It certainly is a sign that we have recovered so much already. I too believe we will be much healthier. To me, as long as I'm not smoking and wasting my life away high and intoxicated, I'm being productive.
