Alex hadn't seen her sister in a couple of days at this point. Since Mon-el had to leave earth she had been acting differently. Neither J'onn nor Lena had seen her in days either. This wasn't like Kara. Something was very wrong.

Alex knocked twice before she just barged right into Kara's apartment. Her door wasn't locked, so she knew she was home, but she wasn't answering. Alex was really worried about her wellbeing. That's when she saw her.
Kara lifted her head slowly, her neck weak and her eyes bleary. She looked at her sister, her expression blank. "What do you want?"
Alex's eyes widened. "Kara. When was the last time you ate?"
Kara looked away.
Alex walked closer, her heart pounding. Kara's collarbone was jutted out, and her cheekbones were far more visible. "Kara."
"... I don't know, maybe two days..."
Alex felt like she had just taken a punch to the stomach. "Two what?! Kara that's a week with your metabolism!"
"... I know."
Alex huffed and rubbed the back of her neck. "Do you ever have food here? Do you want me to- You know what, I'm just going to order a pizza. Yeah, and I won't even try and steal any from you, because it will be all yours. Don't even bother saying no, it has been decided."
Kara only watched as her sister called the pizza place to order. It had been hard since Mon-el left. Maybe it wasn't fair that she had been shutting everyone out, but she didn't know what else to do. Maybe it would be easier to keep people she loved away from her. But she truly didn't want Alex to go.
When Alex had finished the call, she grabbed a glass from the cabinet and filled it with water. She placed it on the table in front of Kara and sat next to her. "Come on, you need to drink. Do you need help?"
Kara weakly shook her head. "No, I got it. Don't worry about it, Al."
Alex waited until her sister was done drinking before she went off on her. "Don't worry about it?! Kara, everyone is worried about you! Look at you! You're hurting yourself and you don't even care! You have to pull through, Kara, this isn't okay!"
Kara flinched. Alex doesn't normally yell at her.
Alex took a deep breath and released it slowly. "I'm sorry... I just-" Alex pulled Kara close to her chest and cradled her head. "I don't like seeing you like this. It's scary. You know your metabolism is way too fast for you to be not eating for days at a time. I know you're sad, but please, don't do this." She kissed the top of her head gently. "I don't wanna lose you." Kara snuggled into her neck in such a way Alex had to bite her lip in order to not cry. "Please don't do this...," she repeated, softer this time.
Kara broke first. "I'm sorry...," she whimpered, weakly grasping onto Alex's middle. "It just hurts... It hurts so much more than this but it's a distraction from the emotional pain I've felt since we had to say goodbye..."
Alex swallowed hard and held her even closer. "I know. I know it was really hard for you. But I'm proud of you. You let him go because you wanted him to be safe. Sacrifice, Kara. I wish you didn't have to keep doing that, but the fact that you've gone through so much and you're still kicking is amazing. Please, don't let this one get to you. You're allowed to find a coping mechanism, but this isn't it."
Kara's stomach growled if only to prove her point.
Alex closed her eyes and rested her chin on top of Kara's head. "You understand that, right?"
Kara nodded. "I know, you're right... I'm sorry, Al..."
Alex finally allowed a few tears to escape. "It's okay, just don't do this again. Promise me you won't."
"... Just don't hate me if I fail."
"I won't hate you, just don't give up, okay?"
Kara let out a shaky breath against Alex's neck. Alex was so understanding; it made her wish she would've let her in before all of this happened. "Okay."
"Good." Alex reached up and began stroking Kara's hair. "I love you."
Kara leaned into her touch and finally allowed her eyes to close. "I love you too." And that's where they stayed until the pizza came, which Kara almost finished on her own, much to Alex's delight. Kara stuck close to Alex's side the whole time after that. She didn't want to feel like that again. Alex made her feel present again.
Alex would squeeze her hand and kiss her head when she would start to feel down again. She wasn't going to let her sister go through this alone. "I'm staying tonight, okay? I don't want to leave you alone tonight."
Kara didn't argue. She wanted her to stay. They both climbed into bed and Kara immediately tucked her head under Alex's chin.
Alex kissed her hair and held her tight. "It's going to be okay, Kara, you'll see."
Kara whimpered and let the tears go.
Alex felt her neck gradually dampen with her sister's tears and began to cry as well. "You won't have to do this alone, I promise..."
