hiya, and hugs back
sorry you're going through this at the moment, and that it sounds like something you regularly have to deal with. i know what you mean about trying to cope by ignoring symptoms, but that's easier to say than do.. maybe distracting techniques might help you ignore them. but - i know the minute you think 'heart' then it's bound to be a trigger for the anxiety, that's why i'm having silly conversations in my own head at the moment, trying to reason it out & keep the panic away.
do you regularly check your blood pressure and/or pulse? i've managed to go the whole day today without doing either, as i almost scared the pants off myself last night when i felt a missed heartbeat twice.
i actually feel a little better not knowing just how fast my pulse is, or how temperamental my heartbeat is right now...
