Help Me, Doctor (Book One of Doctor Who: Be Mine series)

I'm alone. I have had many companions, but sooner or later, they all die. Only one person can make my life complete. After the Time War in Gallifrey, I thought I'd be all alone. Apparently not. A girl I met when she was younger has come back into my life and I can't lose her again. I won't lose her again. But, as always, she's going to die some day and I can't help her. But she does something remarkable and I don't understand. I am the last Time Lord, so I thought.
************************************************** He's back. I haven't seen him in so long. I was only seven when I last saw him. I can't believe he's back! The one who saved me back then. It feels like a long time for me, but then there was him. He travels a lot and for him, it must have felt like forever. The Doctor is helping me through my troubles, and I'm happy I met him. I can't believe the guy that saved me so many years ago is here to help me once again. I lost him once, and I hopefully won't lose him ever again.
