My dearest Doctor,
I have a feeling that my time is coming. It happens to all of us. I knew it was going to be me one day...though I never imagined leaving like this. I don't like being ill, and I wish sometimes you were here with me, to talk to me while I attempt to sleep. But, I'm sure you're having a fantastic time where ever you are and whoever you are with.

When ever I think of you, which at the present is very often, I smile. I smile because I know that you are out there saving planets and giving people hope. I remember all those times we spent together, the nights we shared, laying together and talking about...nothing in particular. Those times in the TARDIS. I used to miss them, and sometimes I still do. But now, when I remember them, I smile.

I never thought that I would actually have to say goodbye to you. I suppose I knew we would run into each other again as time went on, but I know now that there's not much time left to have such things happen.

So, Doctor, if you are reading this, I have passed on, happily and willingly. Luke will fill you in on all the details: how, when, and where. But I am not scared, and I want you to remember that you are always in my thoughts and I will always love you. Goodbye, my Doctor. May you live many more years and do many more things. Please remember your Sarah Jane Smith.

Forever yours,
Sarah Jane
