I find it odd also. There's a couple things that could have set the wheels in motion. In 2020 summer I took some kratom and had a massive panic attack, the hppd worsening might have started then but was very subtle at first. In December 2020 I started having panic attacks on a once a week basis, this is when I began to notice the hppd worsen. Can stress/anxiety alone cause such a drastic increase in hppd? Can't seem to figure out what's making it worse still
