I wonder how biology can explain the physical pain you feel in your chest when all you want to do is be with someone.
Dan Howell (via cnnorfranta)
During periods of anxiety, stress, fear, sadness, or other unpleasant emotions (like missing someone terribly), your body releases a couple of stress hormones—epinephrine and cortisol.
While epinephrine (the “fight or flight” hormone) helps your body respond quickly in the short term, cortisol is like an extended-release stress hormone. An overproduction of cortisol will tell your muscles to tense up, and if they have nothing to do besides curl up in bed or cry or bring spoonfuls of ice cream to your mouth, they will stay tightened up and make you achy and tense all over…but especially in your chest.
