The Doctor runs into the TARDIS, dying and begins to heavily breathe his last breaths. He tries to prop himself up on the rails, he wants to die standing. He wants to die with dignity.
Saving a planet or two, or the universe is easy, at least for the Doctor. At the worst, he gets a scratch and that only happens in a blue moon. However, saving a friend is different. There is always damage. Physical pain, mental torture, death. It is odd, really, one would think it would be more the other way around. But it isn't for the Doctor.
Still no matter how many times he saves his companions, the people who he might for a second give up the universe for, they always end up gone. They will, or have, died one day (except, maybe Jack, but he doesn't really care for him anyway), while he lives on. Over time, he has accepted that fact but not completely.
Well, right now, he is dying alone. Again. First he burns, fire spouts from his skin. Then golden winds encompass him and carry away his personality and body while a new one forms in its place. He accepts that he is going away now. Hell, he might even be able to be with his friends again. He closes his eyes and smiles. The last thing he feels, the last thing he thinks about is the tear slowly running down his right cheek.
The process takes a heavier toll on him than usual. The Doctor's body falls on the floor and sleeps peacefully.
The Doctor woke up and felt drunk. Time Lords who have just underwent regeneration might as well be drunk. The Doctor woke up and grabbed the railings. With a little effort, the Doctor was standing on two legs again.
"Well. I guess it is time to examine myself then." The Doctor said with a smile. It was always fun to discover what the new body looked like. "Oh I got myself a new accent and a higher pitched voice than usual!" Then The Doctor grabbed a lock of long of hair that was an odd mixture of brown and ginger. "My body is teasing myself! I'm still not a proper ginger!" The Doctor yelled. Having a wish only partially coming true can be more agonizing then it never being fulfilled.
After some angsting, The Doctor decided to start walking to the closet. (The Doctor's clothes were baggy and did not fit the new body well.) It was difficult at first. A new body means a new center of gravity.
The Doctor finally entered the closet and started to undo some buttons. Then the Doctor noticed two large lumps. The Doctor groped them. Yep, they were real and the Doctor frowned. This Gallifreyan was not crazy about the idea of man boobs. The Doctor tried on multiple shirts, but none of them were well fitted. After trying on a couple dozen of shirts, the Doctor found a shirt that was formfitting.
The Doctor went up to the mirror to see how the shirt looked.
Wait. The Doctor thought.
Long Hair + Curvy Body + Breasts + High Pitched Voice (tends to) = Girl.
"I've turned into a girl!" The Doctor shouted, laughed and cried a bit at the same time.
This probably because River Song gave me her regenerations. The Doctor hypothesized.
"I'm a bloody girl!"
The Doctor was hysteric and losing some of her sanity.
I originally posted this on deviantart as two chapters and I made some small changes.
It's a bit hard not to include gender pronouns.
