i hate the sound of my own heartbeat

i cannot stand it. i'll be running and i'll feel it thudding in my chest, or i'll press on a vein and feel my pulse ever so slightly, and i'm repulsed. it's so unsettling. i don't have a problem listening to heartbeats belonging to other people, it doesn't bother me at all, in fact it's almost soothing, it's just mine that bothers me. the worst is when you're panicked or you ran too hard and you'll be heaving, trying to breathe properly and your heart feels like it's about to burst out of your chest and bleed everywhere.
