I think anxiety can be so distressing, and the palpitations sound very unsettling. It must be confusing not knowing the cause of the palpitations.
I’m glad that at least a lot of physical causes have been ruled out. While I’m not a doctor, and just speaking as an everyday, unqualified person, I wonder if the palpitations have more of an emotional cause.
I noticed you commented on how they seem to coincide with periods of heightened emotion, and feeds into/exacerbates your anxiety...or is the the other way around, the anxiety feeds the palpitations?
I don’t personally have palpitations regularly, but when I have them, they aren’t painful and tend to coincide with either physical exertion (e.g. strenuous exercise) or peaks in emotion e.g. feelings of surprise, shock, etc.
Hopefully you will get to the bottom of things at your upcoming appointment. Please feel free to chat in the mean time here (or any time), and to let us know how the appointment goes. Granted, there’s no pressure of course...only if you want to. Please just know we are here to support you...
Kind and caring thoughts,
