Love Letter Help

Hi, my girlfriend broke up with me about 6 months ago (yes, I know it was a long time ago). We are both 15, and I know we are quite young, but I know it in my heart, that I truly love her. This is all fine, except that she wants no part of me. The heartache is unimaginable, and so I tried pouring it out into a love letter which I sent her. I just want to get another opinion on it, because I am very nervous. Please read it and let me know what you think.

      Finding these words has been the hardest experience of my life. I have pondered over them for months. Even though I have rehearsed them thousands of times, my hands are still shaking, and my palms are still sweaty. I would have liked to tell you in person, however, there was no time for me to do so. I know that it has been over four months since we ended our relationship, but this is something I need to get off my chest. I know that you probably have heard this multiple times from me, and other people, but I still feel as strongly for you now, as the day I asked you out. I am still deeply and madly in love with you. Every day from the time I wake up, until the time I go to bed, I can't stop thinking about you. Even when I try not to, my mind is fixed upon your beautiful face. I feel that I shared a deeper connection with you than with anyone else I know. I felt like I could tell you anything, and that there was something more than physical attraction between us. I still feel that you are the most beautiful girl in the entire world, and in my mind, you will always be. You are the light of my life, and without you, everything is pitch black. Since the day we broke up, my entire life has been in a downward spiral. For these past four months, I have been holding on to a small glimmer of hope that has been growing dimmer and dimmer as time goes on. I don't want to scare you with this; I just needed to tell you. I do know that you do not want to get back together, and that you hate me. I just feel that this is something I had to tell you. I do not want this to affect our friendship in any way, although I can understand if it does.
