I used to think it was just an expression;
                          a fancy way to say really, really, really, tired.

It's a little bit more than that.

It's
                                                 ­       exhaustion.
It's
                                      defeat             and             despair.
It's
                                             ­         hopelessness.


it's putting everything you have into something, and not making a dent,
it's believing in someone when they don't even try to have faith in you,
it's feeling so tired and knowing you won't be able to fall asleep,
it's seeing the inevitable and accepting defeat,
and not even trying to resist fate because it's sad but there's no point.


that
     is what it feels like, when weariness seeps deep into your bones.
