Sam looked at the food in the diner with distaste, feeling his stomach grumble hungrily. If asked, most of the food sounded yummy, but given his common issue to binge eat everything, he was trying not to eat. He could feel how much weight he needed to lose, and it was really starting to bug him.

He slouched to his seat, sitting down heavily, and watched as Dean filled his plate and returned to the table.

"Not hungry?" Dean asked, knowing something was up with his little brother.

Sam rolled his eyes, mother hen Dean had arrived, as he picked up his glass of water and downed most of it quickly. "Not really, the grease smell was upsetting my stomach." he said nonchalantly.

Dean frowned, but nodded and dug into his food. He stuffed his mouth as full as possible, over and over again, only stopping long enough to take a drink or get another plate.

Sam watched his brother eat, paling as the thought made his stomach churn unhappily. He excused himself, when Dean was on his fifth plate, walking quickly to the bathroom. He barely made it in a stall, before vomiting up all the water he had just drank. He dry heaved weakly, grateful that he hadn't eaten anything.

Once he had vomited and dry heaved as much as he could, he left the bathroom and headed back to the table. He smiled at Dean, who was happily tucking into a piece of pie.

"Almost ready to go?" he asked calmly, trying to pretend like nothing had happened. He didn't realize that he had forgotten to wash up face, leaving traces of spit on his chin.

"Yep." Dean said, immediately noticing the spit left on Sam's chin. He knew his brother had been vomiting... again, and was really starting to worry about it. He tried to play it off, while making a mental prayer to Cas to meet them at the motel. He needed the backup to try to force Sammy to eat something, and he could tell by how skinny Sam was, that he was becoming malnourished.

He finished his pie, without really tasting it, wanting to head back to the motel sooner than later, and getting some food in his little brother. He paid for his food, then motioned to Sam to meet him outside.

Sam followed Dean out to the impala, faintly wishing he had eaten, but not wanting to gain the weight, so he was okay that he didn't. He climbed into his seat, hissing softly as the sudden shift made his stomach growl loudly. 

"I thought you weren't hungry," Dean said, as he got in his seat just in time to hear the growl. 

Sam flinched, quickly shaking his head. "Not hungry." he said firmly, even as his stomach growled again. 

"Sure, whatever you say, Sam." Dean said, trying not to let any frustration or concern appear in his tone. "Movie marathon at the motel?" he asked, knowing he could get Sam to eat popcorn if they were watching multiple movies. 

"Sounds fun." Sam said honestly, oblivious to Dean's plans and attempts. He looked out the window, choosing to zone out instead of continue any form of conversation. 

"I think it might be lord of the rings again, is that okay?" Dean asked, knowing Sam loved anything J.R.R. Tolkien. He waited a couple minutes, before looking over to Sam's side of the car, and seeing that he was zoning out. "We'll work it out." he mumbled, more for this own sake then Sam's. 

Sam happily climbed out of the impala, when they got to the motel, and headed inside. He was so preoccupied mentally, he didn't hear Cas' wings as he appeared. 

Dean waited until Sam was inside to look at Cas. 

"Hello, Dean." Can said, once Sam was out of hearing range. 

"Hi, Cas. I need your help. Sam isn't eating like he should be, and when he does or thinks about it, he throws it back up." Dean said in a rush, his concern taking over.

"He has bulimia." Can acknowledged. "We can encourage him to eat, but he will probably still throw it up." he pointed out after a moment of thinking. 

"That's a good start, hopefully he won't puke anymore." Dean said, praying that deep down Sam would be able to eat and not get sick. 

"Don't get mad if he can't handle much of anything." Cas warned, seeing a look of grim determination on the older hunter's face. "He is very unwell, Dean." he added firmly. "If we can't help him knock this, it could be what kills him. Not a demon or angel, this." he added right after he last spoke. 

"Yeah, yeah. I know." Dean said, waving the angel and his concerns off as he walks inside the motel to find Sam flipping through the tv channels. He looked at Cas whom had followed him inside, before nodding as the angel snapped his fingers making a smorgasbord of mouth-watering foods appear in front of Sam. 

Sam swallowed hard, looking at Dean in confusion, as his face paled. "What's going on?" He asked, his voice breaking silently in uncertainty. 

"You gotta eat, Sammy. Dad would kill me if he saw how sick you are." Dean said heavily, shaking his head. 

Sam shook his head adamantly. "I'm fine, there is no reason to assume otherwise." he said flatly, the emotion in his eyes said that he felt betrayed by Dean's actions. 

"He cares, Sam." Cas pointed out. He knew what Sam was feeling, even as he could tell Sam was starting to feel quite sick. 

"Start with a salad, then eat something with a lot of meat, then fatty." Dean said, laying out the food in order and handing Sam a fork. "No talk, just eat." he said firmly. "Oh and no puking." he added. 

Sam swallowed hard, before doing as he was told and eating everything Dean said to eat. The more he put in his mouth the harder it was on him. The more food went down his throat, the closer he got to vomiting. 

"Dean?" he asked, putting the fork down as his stomach threatened to purge right there. He wrapped his arms around his bloated stomach, before pressing a fist to his mouth as a belch and gag emitted from his lips. 

"Come on, Sam, you're almost done. I promise, one more bite." Dean encouraged kindly. 

Cas stepped up at this point, not wanting Dean to hurt Sam. "That's enough." he said, putting a hand firmly on Dean's shoulder. "Sam?" he asked. 

Sam leaned back, trying not to gag again, as the contents of his stomach sloshed back and forth. He sat there miserably for a moment, before jumping and bolting to the kitchen sink as fast as he could. 

"Sam?" Dean asked in surprise, looking at his little brother in concern. 

Before Sam could say anything, all the food he ate erupted from his mouth and into the sink. He gagged and vomited over and over, filling the sink with everything in his stomach. 

"Dang it!" Dean said, jumping up to check on his little brother. He motioned to Cas to get rid of the leftover food, as he led his little brother to his bed. "I'm so sorry, Sammy." he said softly, feeling really guilty for making his little brother so sick. 

"I'm not mad, just need to take it slow." Sam said weakly, before collapsing on the bed in exhaustion. 

"Sure, Sammy, we will do it your way... On one condition. If we can't sort this out, you will get help." Dean requested, hopeful that Sam would agree. 

"Okay, Dean, I agree." Sam agreed honestly. He fell asleep after a matter of seconds, a tired smile on his face. 

------------------------------------------------------------------------------------------------------------------------

It took a lot of work, and a lot of back and forth between over doing it and vomiting, but Sam finally started to gain weight again and eat like he was supposed to. Dean and Cas were by his side the whole time, helping and cheering him on.
