Well basically whenever I can't feel my hear beating I think it's on the verge of stopping and life fading out. I constantly focus my attention toward the heart area of my chest and am constantly feeling for my pulse. Ironically when I get so worked up that I can feel it pounding oyt of my chest I still feel like it will stop at any second. Other times when I feel my pulse I won't feel any thing for a second and that really sets me off. I know it's normal to not feel it beating unless you feel your pulse, but phsychologically I just can't get over it. I would say I'm aware of about every single heart beat I have every day. Even though I'm aware of my heart beating, I still feel as if it will fail me; even as I type this. It's almost like a conscious effort I have to keep putting fourth every day to keep it beating I know you guys can't do anything to help physically but atleast getting feed back might put me at ease. I've lost about 4-5 hours of my normal sleep pattern tonight just by having an anxiety attack; I have to get up for school in four hours. That is not a good day at school, going on four hours of sleep, that is. Any appropriate feedback is appreciated, thanks!
