I feel that heartache is akin to a stomachache. When you've unspooled yourself from depths to which the other person wasn't perspicacious, you end in re-winding yourself. It's in this process you feel the emptiness as they're not there. You maybe thought they were while they were bodily present but that's over and now as you piece yourself back together, the emptiness tells. It feels so, not good (I'm not a masochist), but real. And that's what I remember about tummy aches and fevers, etc. They're few and far between but they always reset me. A few days since my last heartache and about a year-and-a-half since my last food poisoning episode. It's nice to have a little mirror in the physical for what ails me emotionally.
