I hate being afraid..there is something wrong with my heart.I get scared if its not beating fast and get scared if its beating slow..I take it and the last few days I have been taking my pulse so often I cannot concentrate on anything. I started watching a movie today and had to put it on pause over and over to make sure that my heart was beating not to fast.My heart beats normal 72 during the daytime but for some reason i woke up this morining with it beating a little faster than normal.I took it.. and it seemed pretty normal but for the last few days I have really been obsessing taking it every few minutes..I suppose its cause I can hear it in my head.. it sounds like it beats for the most part normal but it sounds sometimes like its hiccuping...but with a regular beat..I wonder if its just because I can hear it that I might be imaganing a sound that doesn't sound right..I usually am pretty calm or not real paniky all the time but the last few days I have felt a nervousness that I cannot explain.I woke during my sleep and felt really bad..I am not sure exactly how to describe it ..but maybe it was just because of the way i was sleeping..The last few nights I have woke earlier than normal and felt this way..I also notice a little nervousness before sleep..I don't know why im feeling this way but hearing the pulse more makes me worry more.. I know that there are others that said that hearing the pulse is a part of anxiety..When you hear yours does it sound or feel like maybe its coming from the back of your head or neck?I get worried that maybe its an artery that the doctors didn't notice that actally makes this sound in my ears.. But it makes me continually aware of my heart beating and also makes me nervous and I check my pulse.Its like I cannot stop.. I suppose by now if there was really something wrong with me it would have made me quite ill ,I suppose I should just let it go.. but i have always been a secret pulse taker.. and its getting worse..I wish so much that i could just stop..and will try .. Watching a movie tonight although in the first of it i kept stopping it I did better at the middle to last..Maybe I need distractions to make me stop this...I don't know,just wish I didn't hear it all of the time..
