A/N: Hey guys! Well, sorry for the wait on this one. It's my first Cas/Sam/Dean songfic so I hope it's good! One thing is that Mary Izzy Dakota asked me if I could insert her in this one, so I'm going to throw her in as a minor character in this one. She won't be in it very long. I hope this okay with her. Anyways, so ' Mary' is not Sam and Dean's mother. :) Enjoy!

Unwell- Matchbox 20

Castiel/Sam/Dean

All day staring at the ceiling.
Making friends with shadows on my wall.
All night hearing voices telling me,
That I should get some sleep.
Because tomorrow might be good for something.

Sam had not been sleeping well. With the Apocalypse hanging over their heads, he's not surprised. Dean had tried to prod him to get more then one or two hours of sleep at night. But, no matter how hard Sam tries, he just can't.

Sam has tried every trick in the book. Warm milk, calm music, everything. He even threw out the idea of a sleeping had firmly rejected to the idea so Sam let it drop.

Now, Sam was clutching the blankets on the motel bed he was sitting on, knuckles white. He was trying not to lash out at Castiel for some reason. Just his voice was biting at his nerves. It's even worse when he's quiet.

Sam hadn't realized he had jumped up in the middle of a sentence, his brother and the ex-angel looking questioningly at him.

" I'm going out for a while," Sam said in a breathless mess, " don't wait up."

Hold on.
Feeling like I'm heading for a breakdown.
And I don't know why.

Sam fished around in his pockets for some money, sighing when he found some. The next bar was miles away, but there was a liquor store across the street so he decided that it was enough. Sam crossed the street, ducking inside the store and grabbing a bottle of Jack Daniels. He headed off to sit in an alleyway, preferably to hide from his brother when he decides to come looking for him. Cas would probably be with him so they would find him in a heartbeat though.

Hopefully he would be well past shitfaced at the point.

" Uh, hey."

Sam looked up at a girl who stood to the side of him. " Hey." Sam said casually.

" Rough night too?" She asked, sliding down the wall to sit beside him, holding her hand out waiting for the bottle.

Sam sighed and handed it to her, " you can say that."

But I'm not crazy, I'm just a little unwell.
I know, right now you can't tell.
But stay awhile and maybe then you'll see,
a different side of me.

She smiled softly and took a drink from the bottle before handing it back to Sam. " I'm Mary."

Sam lifted the bottle to his lips and took a drink before answering. " I'm Sam."

" What are you doing sitting in an alley Sam? If you don't mind me asking."

Sam chuckled, " I just needed to get away, you know?"

Mary nodded, " I know that feeling."

Sam passed the bottle to her again, she took another drink before asking. " So, what has you down then?"

Sam just shook his head, " the world is crashing down around us, and there is nothing I can do about it. Hell, I feel like I started it. It even keeps me up at night."

I'm not crazy, I'm just a little impaired.
I know, right now you don't care.
But soon enough you're gonna think of me.
And how I used to be...me.

Sam stood as the bottle had quickly become empty. He looked down at Mary.

" It was, uh, nice to meet you. I'll see you around?"

Mary nodded, " It was nice meeting you too Sam. Bye."

" Bye." Sam staggered out of the alley, he was always a lightweight. He let out a breath as he looked down the sidewalk. " What way is the motel again?" He asked out loud. He sighed and walked in the direction he thinks the motel is. He chuckles darkly in his head, he never wouldn't be in this mess if he could just disappear suddenly.

Then again, Lucifer and the demon's would just find him again.

I'm talking to myself in public.
Dodging glances on the train.
And I know, I know they've all been talking 'bout me.
I can hear them whisper.
And it makes me think there must be something wrong with me.
Out of all the hours thinking,
Somehow I've lost my mind.

Sam just chocks it up to the lack of sleep. This whole thing. And to the Apocalypse. And to Lucifer, Dean, Cas, angels, and demons.

But mostly he blames himself.

He started all of this. That he was the person to point the finger at. He's Lucifer's vessel, let's kill him.

That the angels will win. Paradise on earth or some bullshit like that. But, Dean has told him and himself that they are going to say no. And Sam wonders if it would just be easier to say yes, let Lucifer ride in his skin, then hopefully the angels or Dean would be the one to end it all.

That he started it all, so why doesn't he end it too?

I'm out of my mind! Sam thinks drunkenly.

But I'm not crazy, I'm just a little unwell.
I know, right now you can't tell.
But stay awhile and maybe then you'll see,
a different side of me.

Dean sits on a bed in the motel, the lone lamp lighting the room. Castiel had left a few hours ago, and Dean had been sitting on the bed, turning his car keys around and around on his finger. He was about to give up and fall asleep, or just get up and try and find Sam.

He hadn't really chosen yet.

But, as he was going to give up, Sam opened the motel door, mumbling something along the lines, ' thank God he's not here.'

Dean stood, " what the hell Sam? You know what time it is?"

" Time for you to not talk so loud?" Sam asked, giving Dean a goofy smile.

Dean raised an eyebrow, " are you drunk?"

" How can you tell?" Sam walked over to the bed, falling down onto it and looking up at the ceiling. " Yeah, I'm drunk."

" You know, if you have something to say just say it Sam."

" Castiel's voice is annoying." Sam said with a chuckle, closing his eyes.

" You can say that again." Dean muttered, " look, Sam, what's with the drinking bender?"

The only response he got from Sam was a quiet snore.

I've been talking in my sleep.
Pretty soon they'll come to get me.
Yeah, they're taking me away.

Dean stayed up a little longer in case he had to be on hangover patrol tonight. Sam tossed and turned letting out a ' No!' and ' You can't take me!' every now and then. Dean sighed and turned off the light.

" It'll get better." Dean muttered into his pillow, " it always gets better."

I'm not crazy, I'm just a little unwell.
I know, right now you can't tell.
But stay awhile and maybe then you'll see,
a different side of me.

Castiel stood off for a while, waiting with Dean in the shadows for Sam to come back. After Sam had come back and Dean had fell asleep, he walked into the room. Castiel bent down beside Sam's bed as Sam thrashed around and whimpered as if he was in some really long nightmare.

Castiel wished he could do something to put the youngest Winchester into a peaceful sleep. Sam yelled something incoherent as he shot up out of his bed, taking a swing at Castiel in his wake. Castiel grabbed his arm, Sam looking at him.

" Cas?"

Castiel let go of his arm, " you were dreaming."

" Yeah, I got that." Sam pulled the blankets off him and went to lean forward against a table. " I think I'm going to be sick..."

Castiel glanced towards Dean, who was still in a deep sleep. Sam shook as he tried to push himself upright to make an effort to get to the bathroom. Castiel thought that Dean wouldn't appreciate vomit on the table the next morning. He quickly put Sam's arm around his shoulders and walked him to the dark bathroom, the two stumbling around in the dark before Castiel set Sam down on the edge of the bath tub before Sam retched into the toilet.

Castiel sat awkwardly beside him, placing a hand on Sam's back. Sam pulled his head out of the toilet after about ten minutes of vomiting and five of dry heaving.

Sam looked at Castiel, looking sleepy.

" Thanks, Cas." He mumbled, standing on shaky legs and wiping his mouth. He was tired and didn't feel like asking Cas why he had been here in the first place. Sam walked back to the bed and lay back down, quickly passing out into a deep, dreamless, sleep. The first he's had in months.

Castiel watched him for a few seconds.

" Goodnight, Sam." He said before turning to leave.

Yeah, how I used to be.
How I used to be.
Well, I'm just a little unwell.
How I used to be.
How I used to be.
