When we are in darkness, we need to know there is light somewhere.
It may take a while to get out of, and feel strange when we are finally free, because we have grown accustomed to desperation.
But everything in life serves a purpose- it may not turn out the way you planned, but every experience was meant to teach you; about yourself and others, and to connect you with the universe.
With that realization; every heartache, loss, and tear shed is a lesson; one to look back on, smile, and say: I've learned from it, and am now a better person because of it.
