Closest road to heaven

Hello my dearest person,
I'm afraid I love you.

I was blinded by dejection,
My delusional self strong.

You exist solely on my illusion,
Though the closest warmth you give.

I know I'm insane and causing unwanted confusion ,
But you are and what keeps me sane.

This little short story is just something that happened to be a school-related work, but I guess I decided to re-write it again, correcting some parts and adding new stuff to it too.
The plot was thought of by two of my friends and I, and I eventually developed it into this. Honestly, I had a lot of help from my friend, after realizing how much I sucked in developing decent English sentences. Please bear with my pathetic attempt to sound intelligent and also my ignorance on what exactly the character in the story is suffering from, I'm sure there's a proper name for it.
But it is fiction anyways, and I am not in any way having the intention of offending anyone, so yeah.
Oh and I know my "poetry" is absolutely crap, it doesn't even sound right but I tried.
