i'm a 25 yr old woman and i suffer everyday from irregular heartbeats and dizziness, (like the walls are moving and im going 2 fall over) and i also sometimes get the strangling sensation in my throat. i have worried myself silly over these feelings, i have lost sleep because i believe i will not wake up, i have taken myself to A&E because i've believed so much that im goin to die any second! im beginning to become desperate, ive had countless ecg's and everything is always normal and clear. but yet i worry that there is something more severe and the doctors are missing it.. my symptoms are much worse after a night on alcohol, so i have now stopped drinking for fear that it will kill me!! i have just discovered this site and i am hoping that it can make me feel better knowing that i am not alone in this lonely scarey world.
