You had consumed the time vortex, the heart of the TARDIS, to save the Doctor from dying a tragic death by Daleks some thousands of years in the future. Thing is, it wasn’t meant for anyone to see, let alone consume and hold in their head. It was too much.

You stepped out of the TARDIS and removed all the Daleks around you from existence to protect the Doctor, like you told yourself you had to. You loved him, you couldn’t let him die like this. Not after all he’s done for you.

“What have you done?!” He asked, exasperated. He wasn’t mad, he was incredibly worried.

“I have become part of the time vortex.” You said in a monotone, almost as if you weren’t you.

He was panicked now “This is wrong! You can’t control life and death!-“

“But I can.” You cut him off. “The sun and the moon. The day and night. But why do they hurt…?”

“Their powers are gonna kill you and it’s my fault!” He said, terror deep in his tone. He was terrified of losing you to this.

“Please… let go of it… it’ll kill you and I can’t lose you…” pain stayed in his throat and eyes. He could swear he saw your life drifting from your eyes. “Give it to me… I can send it back but you need to let it go..” he pleaded.
