In the end everyone will hurt you... it's up to you to decide who is worth the pain. Not all scars shows. Not all wounds heal. Sometimes you can't see, the pain someone feels. Someday everything will all make perfect sense. So for now, laugh at confusion, smile through the tears, and keep reminding yourself that everything happens for a reason.
It's just one of those days where you lock yourself in your room, crank the depressing music, curl up on your bed, and cry for no reason at all.
