My heart rate has dropped to it's 50's....I checked it on one of those iphone monitors (it checks other things as well) and it says my body is too relaxed and in 'danger' and my body is stressed due to illness.

My resting heart rate is always in the 70's so this is weird for me. I feel spaced out and weird now and I don't know if it's anxiety from the reading. I keep checking it and it's only getting worse. I'm so scared.

I'm on my own, I'm scared I'm going to black out and die. I don't know what to do.
