The body's emergency pressure valve, leaking proof you cared too much.
means To weep with audible, convulsive catches of breath — crying hard enough that your body shudders with it.
from From Middle English 'sobben,' likely imitative — a word built from the sound itself, that ragged hitch of breath you can't smooth out. It's possibly related to Old English 'seofian' (to lament) and has cousins in the Dutch 'sabben.' Either way, the word does what the act does: it stutters.
