Make this all stop

A please help
Stop this pain and stop me from causing more pain to myself. You mean too much to me and you will never understand. You say you are going through the same thing with her but there is no way you can feel this way when I have know and loved you since we were 5....5! That's too long to love someone who doesn't love you back but yet I still love you
Is there any way I can help you realize that she doesn't care about you or how you feel like I do, she doesn't care if you are having a bad day like I do and she doesn't care if you love her or not.
