(Sam/Reader) Help Me

I can hear the yelling in my head, my muscles tense. It won’t stop. I sit in my room curled up on the floor. Why does this always happen to me? I can’t handle it anymore. I need to run, just get away. I feel my heartbeat get faster, my hands start to shake. It’s hard to breathe. It won’t stop. My hands find their way up to my ears, trying to block out the noise coming from my head.
“Please STOP!!” I hit my head as I say each word. I can’t take it anymore. Tears stream down my face. I jump a bit as the door opens.
“Hey, are you okay? I heard some loud-” He swoops down before me when he sees me. “Hey, hey. What’s wrong?” Sam gently takes my arms away from my head. I flinch slightly, the yelling still won’t stop. He wipes the tears from my face with his thumb.
“Hey,” he tries to make eye contact “What’s wrong? Are you hurt?” He looks me over while I shake my head.
“No, Sam, I’m fine. It’s just-I just” I’m cut off as a sob heaves from my chest. I lean forward and cling onto him for dear life. He just wraps his arms tightly around me, waiting for me to be okay. He moves me so I’m sitting on his lap. I feel his lips on my hair while he whispers sweet nothings.
“It’s okay. I’m here, you’re safe. Shhh, calm down. It’s okay.” He rocks me back and forth as the yelling slowly subsides. I slowly relax and my breathing returns to normal. My eyelids get heavy with exhaustion and I lean into Sam’s chest more. He feels me calm down and pushes me back so he can see my face.  
“You okay? What’s wrong?” He brushes some hair out of my face and looks at me with concern. I nod my head and lean back onto his chest.
“Yeah, I’m okay now. I, um, I can’t really handle stressful, uh, anything really. I mean with hunting and stuff, it’s easier, but sometimes I just freak out like that. I’m sorry.” He rubs his hand over my arm and rests it on my shoulder.
“How often do you have these types of attacks?” He looks down at me again.
“Not often. Sometimes I’m just trying to remember my old life. Y'know? Then I remember how crappy it was. There was always yelling and screaming, I couldn’t take it. I just had to leave. Then I think about how they’re still out there and how they could find me and-” My breathing picks up again and I clutch my hands on Sam’s shirt again. He rubs my back.
“Hey, it’s okay. You don’t need to think about that. Come on, you know you’re safe here, right? Dean and I will never let them take you, even if they found you.” He puts his fingers under my chin, making me look at him. “Now let me see a smile.” I try my best, only producing a small, unenthusiastic smile. His smile widens as his fingers make their way to my ribs, making me squeal and push his hands away lightly. A toothy smile is on my face before I know what’s going on.
“There’s that beautiful smile.” He says softly, a triumphant smile on his own face. He kisses my forehead and stands, with me still in his arms. He lays me down on my bed. As he walks away I grab his hand and he turns around.
“Thank you, Sam.” He smiles and squeezes my hand.
“No problem, and I’m always here if you need help, okay?” I nod my head. “Good night, sweet dreams.”

“Good night, Sam.”
