i don't mean misspeling. I want it sounded as if it was written by a native speaker.

While I was in the US, there was a girl who I admired, who I fell in love with, although she didn't know me at all. She was so beautiful. and I was fascinated by her beauty. Actually I am still fascinated. She was the most beautiful girl I had ever seen, at least in ***. In spite of the beauty, she looked lonely. It seemed strange to me.But the really amazing thing was that she was working at **.I have no idea why she was doing that. I mean to say she was like an angel in that horrible place. I was walking around the location where she worked quite often, pretending that I came
there by chance. I was afraid of starting conversation with her. As you can see my English is far from perfect, that was the reason, and the other one was that I am shy.I swore myself a lot of times for cowardness. But I couldn't do anything about that.Once, in the middle of September I saw her for the last time. It was early morning. the weather was nice and lovely. White clouds were chasing each other in the deep blue sky, and the sun shone brightly.She came out from her dorm, lit a cigarette, and sat down on a step of the stair. She looked sleepy and bored. I was sitting on the bench not far from there, separated from her by the fence. That time I was determined to go and talk with her because I knew that it was my last chance to do it. But I decided to smoke a cigarette first before going to her.I took out a pack of cigaretts from my pocket, and started smoking. By the time I was done with it, she had been gone. And I've never seen her since then.
