In the fanfic, her character could be shown in a more introspective light. Since she's confined to her bed with the flu, she has time to think about her life, her relationships, and her future. She might have flashbacks to important moments in her past and realize things about herself that she hadn't before. This could lead to some character growth once she recovers from the flu.
Her sister could be worried about her and constantly check on her, bringing her warm soup and medicine. Her friends at the stables might offer to take over some of her horse - care duties so she can rest.
In this fanfic, the story could start with Amy Fleming waking up feeling really sick with the flu. She tries to hide it at first because she doesn't want to worry anyone. But as the day goes on, her symptoms get worse. She might have a fever and start coughing a lot. Her horse might sense that something is wrong with her. Meanwhile, there could be a big event coming up at the ranch that she was supposed to be a part of. The rest of the story could be about how she manages to either participate in it despite the flu or how she has to let others take over while she focuses on getting better.

Amy Fleming and Ty are likely characters from a particular series or fandom. They could be characters who have a relationship, perhaps friends or more than friends.

Definitely Ty Borden. He and Amy have a special relationship, so he would be deeply concerned about her illness.

She could be helping Lou with the ranch work and also spending time with Amy, telling her stories to keep her spirits up. And then there's Spartan, Amy's horse.
