I still don't have the hang of it.

When I have symptoms, I believe I'm sick or something of that nature.

Docs run all kinds of exams that come back negative, but sometimes I have high pulse, higher blood pressure and so on, and I feel on edge, but I don't know if it's from the symptoms, or I create the symptoms by the way I'm feeling.

How do you differentiate between the two? I always say - If I think it's stress I will manage it, but I'm never sure it is.
