It's okay. Cry even if you don't know exactly what  you're crying for.
Sometimes we're just too tired of many things. Of being strong for too long. Of wandering too far,
Of carrying things all by ourselves and not being able to come back home.

But also know, sometimes it's just alright to be too tired because sometimes 
it means you did and kept doing the right things. It's just it did not end as early as
you expected it to, or too much more than you thought you could handle.
But sooner or later you'll see things get better.
And all that will remain to you is pride.
