This is my first fanfiction so please be open minded. And i am sorry for bad grammar but english isn´t my first language :] So anyways here we go...

I let the pen slide out of my hand as I finished the last word. Tears blinded me and I brought my hand up to wipe them away. I couldn´t risk the letter getting ruined, not after I spent three hours writing it. It wasn´t long but it held my entire heart. One last time, one last time I was going to read it before letting go. I wiped another set of tear away and stared down at my own words.

Doctor. Oh god only thinking about you kills me. But I have to do this, I have to leave something behind for you. You didn´t know. Or I hope you didn´t. That day, two weeks ago, when we stood here at the beach. You, me and the human doctor. I needed you to say the words, I needed you. I am so, so sorry. I can´t believe I did that, kissed him in front of you. But the thought of you and me together again was the only thing that kept me going, I know that you love me as much as I love you. But he said the words that you couldn´t and I pretended that it was you. And you left in the TARDIS, flying away to save the world. You gave me a piece of yourself that could stay with me forever, grow old with me, have kids. But only seconds after the TARDIS had disappeared totally something happened. The human doctor fell down in the sand. As I bent down next to him he started to disappear. It was then that I understood, he could not be separated from you. We were very alike that way. He looked at me and he said "Rose Tyler I—" and then he was gone. You were gone. The connection with you, broken forever. I hardly remember anything after that, what did I have left to live for? And that takes me to this moment, right now. Here at the same beach were I last saw you. Last week I decided that I couldn´t take it anymore. I am so sorry, doctor, to let you down this way. I know you think more of me but I have lost my heart, my home and everything else. When I was sure I was going through with it the rest was easy. Dåelig Ulv beach, where else? Yesterday I left the house were my parents and their son, my brother lives. They will be sad, of course but I can´t do this anymore. When I got here an Ood was waiting for me. He told me about a crack in the universe, just big enough to send you a message. So I wrote this, the last thing I will do before giving myself away to the waves. I will watch the sun go down, one last time. I can´t explain how sorry I am and I hope that one day you will be able to forgive me. Goodbye.

Forever,
Rose

It was the best I could do, I felt so much more but no words are able to describe it. I folded the paper together and turned around. The Ood stood there silent, waiting for the letter.

"Thank you for doing this."
The ball in his hand light up as he spoke.

"The doctor is important for our survival. The Oods have the ability to leave the universe unaffected when traveling through universes but the message will be just enough to fit in the crack. If I do this, the whole rase of mine are more likely to survive."

It was the longest speech I had ever heard from a Ood and I could do nothing but nod in response. Tears flooded my eyes once again and I let them fall down my cheeks. I handed him the letter and watched him disappear into thin air.
As I sat down on the cliffs, feeling the sun on my face, the last sun I would ever see.
