freaking out....

so this afternoon i was running my usual route by my apartment and was just about to start mile 3 when i started feeling this tingling sensation going down my right arm. i immediately start freaking out because they teach you in nursing that this tingling sensation is one of the signs of an impending heart attack. i stop running and i take my pulse. it was hard for me to breathe so i was seriously scared and like totally freaking out. i had no cell phone and no one was really around. i just quickly walked the rest of the way home, a little bit terrified. I kept on thinking how helpful it was to know that maybe i could get a heart attack, i know the signs and symptoms, but if i did, i couldn't do anything to save myself!!! ahhhh

anyways, long story short, i freaked myself out, damn nursing assessment skills!! or maybe its paranoia?
