I Can't Talk about it !

It sucks to keep a secret ! .. and it sucks even more when you can't talk about this little secret to the ONLY person you feel comfortable discussing such a subject with !
And all that is just because that person just doesn't like talking about that subject that's bothering you !
I don't really understand ! .. I mean I know that life isn't fair ! But aren't Friends supposed to be there for each other, aren't families are meant to support each other !
Then Why is it I am always there when someone needs me !
why is it I am always Ready to talk about anything on that persons mind !, so that she knows that I will hold her hand every step of the way !
But when I Come to her , when I Start mentioning the subject, her face changes and she gives me this look which says : " Stop it there " which totally says : " Don't Complete ! "
Why Does She Roll Her Eyes , and Starts staring at the ceiling when I Talk to her about it !
Why Does She Do that !
I'm Lost .. and I need someone to hold my hands this one time !
Why is The only person I see is NO ONE !
