hello- I am a 37 year old female, 5ft tall, do not smoke or drink, but I am a coffee and tea drinker. A couple of days ago I felt this feeling of anxiety in my chest. To best describe it, it felt as though I was looking down a cliff and felt anxious. I hadn't felt it since, however today while I was shopping at the mall, I began to feel faint and a little anxious. When we made it to the car I was ok again. We drove to a restauarant for dinner and while we waited for our food I toughed my neck to feel my heart beat and it felt as though it was pausing on occasion. I'm not sure if this is what was really going on or not. I also took my blood pressure about 5 days ago at a local pharmacy and it read 106/68, is that considered low?
