Just please tell me why;

Why is it so hard for someone to just admit that they're hurt?
Why does is always come out as anger?
Why is it so much easier to try to hurt others when you're feeling pain too?
Why do we say things that we don't mean?
Why do we love those that can never love us back?
Why is it so easy believe that someone can change?
Why are people blinded so much by their emotions?
Why does thinking of all of this make my head hurt?
Why does thinking of all of this make me think of you?
Why do I still continue to let myself hurt because of you?
Why do I still have those moments where I can't help but miss you?
Why do I still cry?
Why can't I bring myself to say that I hate you?
Why does this still hurt me?
Why do you do the things that you do?
Why can't I believe your?
Why can't you prove that you're sorry?
Why do I hurt so badly, while you sit there in smug happiness?
Why does she get everything that I always wanted?
Why does she get the fairy tale ending when I'm the one who worked so hard; who earned it?
Why is this happening?
Why did we fall apart?
Why didn't you keep your promises?
Why does everything remind me of you?
Why am I still here?
Why is life so unfair?
Why?

Can you please just tell me why?
