The Wait *destiel*

Day 15.

Cas' final day.
I'm sat next to his bed, his hand in mine. I'm talking to him, again, telling him what is happening just in case there's a slight chance he can hear me. I apologise over a million times, saying how I wish I could go back, change it all.
But I know I can't.
This is my fault and I have to live with that guilt and pain for the rest of my life. I start to cry. The tears slowly falling down my face and dripping onto Cas' hand. I wipe away the tears as the doctor walks in.
The doctor puts his hand on my shoulder, trying his best to comfort me. I'm all alone, about to watch my boyfriend die. I asked nobody to come along today. I wanted to say goodbye alone. The doctor is about to turn it off but I remember I didn't tell him I loved him.
"Wait!" I shout.
It's too late.
I turn away.
I can't look. That's it. My angel. Gone. Taken away from me. The tears begin to stream down my face now. I kneel beside his bed and grip his hand as tight as i can. I begin to mumble "no" under my breath. "This can't be happening." "Why."
I sit there trying to control my breathing. It takes me a while but I finally calm down a bit when-

"D-Dean?!"
