To overwhelmedteen: Not all exibit distinct physical symptoms, some exibit very few. Me personally only really exibit anything physical when I'm on the verge of doing something radical during a panic attack like calling the police to come pick me up before I do something terrible(which is not something I think I will do, it's just that I fear I might do it, and my outlook on the world gets coated with a couple of extra layers of anxiety). But thats when It becomes extreme. For example right now as I'm writing this, I have very strong fears that our planet will all of a sudden collapse within the next hour, fear that I will kill myself in the next hour and worry about whether or not I'm evil. My puls is at 58/minut, a bloodpressure of 105/72, no shortness of breath, no light headedness, no shaking, no trembling, just a tad restlessness. what you are describing doesn't necessarily confine your condition to general anxiety disorder, but you can be very certain that whatever it is you are dealing with, It is brought on by anxiety. I'm not a psychiatrist or anything like that, but I have been compelled to read up on a lot of stuff. Which is something you must never do if you scare easily like me. As a hypocondriac you will feel compelled to look up other causing deseases, maybe even theorize yourself, but they will only bring more anxiety, just trust the docters.
