There seems to be a fist (lightly) clutching my heart in it's hand. I can feel it tighten when I breathe. Steps make me feel slightly faint. I can feel a rapid heartbeat when I'm resting (on occassion). My pulse seems to be slightly elevated (very, very slightly) when things finally even themselves out.

I also have reason to believe that my sensitive stomach (due to food poisoning) and my ulcer(s?) contribute to my habitual feeling of general malaise.
