Well today started with the inevitable weak heartbeat feeling straight away when I woke up. Get a feeling like its only doing one beat (should beat dum-dum, mine feels like just a dum). Felt extremely dizzy and had quite a few palpitations. Started bringing up thick white phlegm, almost thick like glue, and some bits were tinged with pink (assuming blood as hadeng eating anything that it could be). Went to check my pulse on left wrist and couldn't feel anything, put my hand on my chest and again could feel nothing. First time this has happened. Cue panic attack!! Huge panic attack lasting about half an hour to the point I nealy passed out. Mum was sitting next to me but nothing could calm me down. Have spent the rest of the day lying on my bed terrified with my mobile next to me just waiting for me to dial 999. Haven't done so yet! I'm absolutely terrified and getting worse every day. I am now adamant there is some major heart problem that the docs are missing, but if I go to docs or hospital I know the first word will be anxiety. I looked up mitral valve prolapse and am convinced I have a valve problem now as it can only be detected by an echocardiogram which I haven't had. Don't know what to do, got so many air bubbles in throat I can barely breathe.
