Like after a rainstorm.

   The nights where you cry yourself to sleep, and the tears keep flowing and they never stop, and your pillows start to feel damp, and the side of your cheek gets cold, so you're forced to turn to the other, drier, side. But the tears still keep coming till your whole pillow's drenched, and you just give up and lie there on your wet pillow, till your hair and your cheeks slowly moisten.

   And there's something about the short period of time where you've finally cried so hard you can't cry any more and right before you fall asleep, where you feel tired. Both mentally and physically exhausted, and that's all you feel. You stop thinking about everything else and sometimes you forget the reason why you were crying so hard in the first place, and the only thing you're able to feel is exhausted. And that feeling, it's so amazing because it feels like a kind of relief after feeling so much pain.
