So it feels like my hearts just going to give out on me

I've had anxiety since I was 14 and I understand how you feel. I was tested for health problems too and then diagnosed with anxiety. Have you gone to a therapist? That helps a lot and they can give you medication for it if it's really bad. And if he therapist you have isn't working for you change therapist. That helped me alot

You have a condition called Anxiety, You are not dying or any other problem associated with death.

You could try Breathing Exercises, or Relaxation Techniques Mindfulness is recommended by GPs etc, you will find books on Amazon.

Its a common case of panic attacks and anxiety. The thing to understand is that panic attacks are not dangerous.it feels as though yr going to have a heart attack and then your breathing gets faster yr hands get clammy and then you get very lightheaded and start pacing around the house like a headless chicken.am i sort of right here? I too started off like that and its so scary and nobody who hasnt had it will not understand. Try to not think about it to much. Distraction is the key..a panic attack is a fear of fear.a fear of having another panic attack.and the anxiety that comes with it is horrible..
