It sounds like you are having lots of panic attacks
, and these in
turn are causing the
rate and the
flutters. You probably notice them more when you are sitting due to the fact that you are not doing anything to distract yourself, and sometimes, the heart will calm down when you are walking, etc.
I have anxiety attacks, and it is a vicious circle, the more I worry, the more heart flutters, I feel, the more heart flutters I feel, the more anxious I get, ugh, it is awful.
