I don't own Supergirl.

AU where Kara is human.

A/N: This is a prompt by Xio. Sorry I don't know much about chronic illnesses, but I gave it my best shot. I'm hoping its alright. Anyway, feel free to leave more suggestions and I will give them a go as well. Or check out my other story Little Supergirl, it's a different take on the Danvers sister's relationship but just as fluffy. Hope you enjoy this chapter!

Alex woke up to the sound of annoying beeping. Slamming her hand down on the alarm clock, she stretched and got out of bed. It was half six and Kara had to take her first set of pills at seven. That gave her just enough time to get ready for the day. Hopping out of bed, Alex got into the shower and then quickly got dressed. Another alarm went off, one in Kara's room. Opening one of the cabinets in the kitchen Alex took one set of the organised pills and headed into her little sisters' room.

"Morning Kar," Alex helped the blonde sit up better and passed her a glass of water, individually passing each pill to her sister after she swallowed the previous one.

"Morning," came the soft reply after she had taken all the pills. Kara was always especially tired in the mornings, the pain she felt often made it hard to fall asleep.

"Let's get you ready," Alex's voice was soft. Kara gave a small nod and let Alex guide her out of bed. The two of them made there way to the bathroom and Alex set up the shower chair, to help her sister out. The blonde found it difficult to stand up for long periods of time without support. Helping her sisters onto the seat the brunette turned on the shower and left the room reminding Kara to call if she needed her. Alex headed back into her sisters' room and grabbed some clothes for her.

"Alex," a gentle call came from the bathroom and Alex heard the water shut off. Heading back into the bathroom, Alex saw her sister wrapped in towel and half slumped against the sink.

"Oh Kar," she said in a half sigh, half laugh kind of way, "I keep telling you, let me help you out of the seat, don't try and do it yourself, its too tiring for you honey."

"It is not," Kara said with a humph, crossing her arms across her chest. With this small action Kara stumbled from her position and started falling to the ground. Quickly Alex swooped in and caught her before she hit the floor.

"Fine, fine, you've made your point," Kara said, "thanks for catching me."

"Always." "Now, let's get you dressed."

Kara made her way over for the table on her crutches. Alex had made breakfast, her specialty, blueberry pancakes. Smiling Kara sat at the table,

"My favourite,"

"I know, that's why I made them." Alex winked at her sister.

"Hmm, these are so good," the blonde said, her fifth pancake in her mouth. She could eat such an impressive amount; it continuously shocked her sister.

"I know, and don't talk with you mouth full," she chided gently, before adding a couple more pancakes to her sisters' plate and one more to her own.

"Now do you want to try to go out today?" Kara nodded her head,

"I've been cooped up in this house to long. But maybe just a short walk, I'm kind of tired."

"That's alright, we'll go on a short walk, maybe to the shops and back I need to pick up some things."

"Sounds good," the blonde nodded again, swallowing another mouthful of pancake.

"Alright let's go," Alex put a coat on her sister and opened the door,

"After you my lady," the brunette made a sweeping gesture through the door to emphasise her words. Laughing Kara slowly made her way out the door, putting her weight on the crutches for extra support. The two stood in the elevator laughing together, before exiting the apartment block and making their way towards the shops.

"Alrighty then, I need to get more flour, pasta, fruit and milk." Alex recited the list to make sure she would not forget it.

"Donuts."

"What?"

"Donuts," the blonde repeated,

"Please elaborate."

"We need donuts,"

"No, we don't,"

"Yes, we do,"

"Fineeee," Alex made sure to drag it out. No matter how hard she tried the older sister couldn't say no to the younger one.

"Yay! Thankyou."

The two were heading back towards the apartment when Alex heard her sister's breathing become louder and more ragged.

"Are you alright sweetheart?" Alex questioned

"Fine, I'm fine,"

"Your tired," the brunette pointed out the obvious

"Yes, but I can make it home I'm alright." Alex could tell that just talking that much was tiring her sister out exponentially. Without saying another word, Alex scooped up her sister and held her against her hip. Taking the crutches in her other hand, Alex ignored the cries of protest from her sister. Afterall, what was the use of having an older sister if she couldn't be overprotective. Kara stayed in her sister's arms all the way home and was only put down when her sister set her on the couch.

"I was alright."

"Of course, you were," Alex said with a smirk. Kara rolled her eyes but didn't say anything more. Her sister was right, she was almost always right. That didn't mean Kara had to tell her that.

The two sisters had just finished watching the Wizard of Oz. Kara was curled up on the couch next to her sister, she whimpered a little when Alex got up.

"I know, but you need to take your medicine again." Heading towards the cabinet of medication Alex grabbed the next set of Kara's pills from the organised box. With them, she brought over a glass of water.

"Here you go hon,"

"Thanks." The blonde said gratefully, and she swallowed the second set of pills one by one like last time. Kara insisted that she could take them all at once, but Alex had put a stop to that idea immediately insisting that it would be much safer to take one by one.

"Ok dinner time I think," Alex said ruffling her sister's hair.

"Pizza?" The blue eyes were wide and hopeful.

"Sure."

It was late and the two had finished serval pizzas each. Kara wasn't the only one who could eat a lot. "You're tired." Alex pointed out the obvious a second time that day. This time though her sister didn't deny it.

"Yes."

"Alright hon, let's go to bed." Alex helped her sister get changed and ready for the night.

"Can I sleep with you," the request was quiet, Alex knew Kara must be in pain because she didn't ask to sleep with her that often.

"Of course, sweetheart, do you need a painkiller." A small nod was the response. After taking the final pill of the day, Kara snuggled into her sister.

"Thank you Alex. I love you"

"Love you too honey, so much."
