What happens when

What happens when you've loved with all your heart and that's not enough when things go from good to bad and the person who said they would always be there walks away.... what happens when he leaves you sitting with tears falling down your face no one to talk to so you stare out of space.... what happens when you feel so down it feels like it's nothing you can do and your friends never come around to comfort you.... what happens when the stars stop shining in the sky and the sun is no longer bright and you stay up all night feeling like you want to die
