you can go into the doc and have it tested but the test is one hell of a test to take. i think what is going on with you is normal. i suffer a little from anxiety
and am a pretty jumpy person. first of all everyone that knows me knows i am the jumpy one and i admit it. and then i laugh about how silly i am. there have been a few occasions i thought i wasnt going to come back from a thrill or two. my favorite was late at night i was going to my car and this guy waited till i got near his car and sit off his alarm. i about died. littlerly i think.
