I'm not really sure whether you could class this as a poem. Probably more of a 'head thought emptying' paragraph type thing :S Ermmm, If he hasn't called yet, I'm sure he's just busy. From what you've said you've done for him, I don't think his feelings for you can change within a week, but then again I don't know what your relationship is like with him.
Anyways, I'm sure you're not alone in thinking this, everbody has some days when they are EXTREMELY insecure; Myself included.
Take care of yourself.
