Update on the heart issues from last time! I went to a doctor two separate times and got a bunch of tests done (all were good news, i.e. no heart disease). I was having stress-related muscle twitches and heart palpitations, and this apparently caused continuous anxiety attacks that kept the heart palpitations going :x. I've been doing breathing exercises and getting more exercise in general and haven't had a problem for almost two weeks now :)
Knowing all this, I can definitely get back to my normal pace with pages, I've just been advised to take steps to prevent stress/anxiety more often :o. So far this has been working well, so sorry for the alarm last time :).
Thanks for reading! :D
