My heart.
I cannot describe how tired and small it feels.
I want to scream into air, one million sound waves of hurt and pain echoing away from me.  I want to run to a place where I can feel nothing, where cold can numb what's left of this husk of heart.
Most of all I want you to notice me.
I want you to want me, to hold me and to love me.  I want to be enough, to be your everything.
It sickens me that I am so weak, that here again I am wondering why you are always wanting more when I should be stronger and wonder what's wrong with me that I want to be with someone who is forever causing me pain.
I wish you loved me.  I wish I could picture a life without you, but I can't.  My best friend is a stranger, my lover sleeps alone.
And then brick by brick, there is another wall around this ever-shrinking heart of mine.
