Grammar & Syntax correction

Hey !

Could I have a feedback concerning grammar and syntax about the following letter please ? =)

Thank's in advance

Emily,

I live only of the happiness to look at you. My eyes are my heart, my eyes are my lungs.
And when by challenge I close them on your way, it seems to me that my whole body suffocates...

Emily, you sometimes pass near me and you do not know, you do not know my nervousness, my love, my glance.

You do not know that I sometimes hate the person who takes place between us, to like him as soon as he leaves and returns you to my sight.

Emily, you sometimes cross me and you do not know that every contact is a suffering, and if you do not know, it is that too much love and not enough courage make of me a ghost.

This letter which I wanted so beautiful has the ugliness of the anonymous letters.
Accept nevertheless that I send it to you without waiting for anything in return, but by hoping that it will tistify you with the only happiness of knowing you loved.
You are beautiful, incomprehensible and never disappointing, never I shall have you; I am inconsolable.
Accept nevertheless,

Emily, my sincere and feverish anonymous feelings.
