Essentially

Affection is, in essence, uniform in its entirety. Affection from separate sources may seem, from certain viewpoints, fundamentally different, but it is only different shades or qualities of the same liquid, all held withing the same glass that is you. Therefore, if you have so damaged yourself as to not be able to hold a fundamental type of affection, namely self-appreciation, you have critically cracked your metaphorical "glass"--the damage is not limited now to an inability to self-adore, but encompasses all areas of affection-acceptance. Essentially, losing the ability to love yourself will render you unable to be loved by others; they can feel love towards you, but you cannot accept it as genuine. It will feel as contrived as all the adoration you have counterfeited for yourself. 

My glass is cracked. I can genuinely feel for you, but I cannot accept this emotion in return, for I am unable to realize its authenticity. I have damaged myself, and you nor anyone else can repair me. Perhaps time will allow me to become a man that I do not despise, to form a glass entirely different with which to store my affections. As it is, however, I leak your and everyone else's affections from my fissures and seams. If I could genuinely accept your adoration I would not have disregarded it so rudely--I would have been able to cherish it with deepest regard. Instead I doubted it to the point that it lost its obvious value. I have broken you by attempting to accept you with my broken self, and for that, I apologize.

Incredibly insightful; profoundly sad.
For he who is afflicted, there does not appear to be any real solution. But people are not broken glasses--though, in fairness to the author, I realize he is only offering an analogy. Yet, he, more or less, based "proof" of his fatal flaw and inability to be salvaged on this analogy.
A poet, of course, can pretty much do whatever he likes in his own writing. He simply has to guard against allowing his great talent for manipulating emotions to manipulate his own.
An extremely well done, very convincing story!
