I love the heavy metaphors within this piece.
The very first line is the most important here especially with the word windows. I believe what you were going for there is that eyes are windows to the soul. And in the next two line you use short sighted and blinded which both enhance the first line.

I believe there is another hidden message here as well. I also think you were going for that you were also tongue tied. Perhaps even forced into silence by this person and never really able to speak the words unless you wrote them. Almost like poetry has become your new voice or your voice altogether.

The story here is well written because it never strays from the emotion you were trying to convay as a whole. There is sadness through out and as the reader i clung to every word because i felt everything you said. I saw no mistake at all. Thanks for sharing
