Final answer:
Guadalupe's feelings are likely caused by a lack of endorphins and the circumstances surrounding her injury, leading to depression.
Step-by-step explanation:
The BEST explanation for Guadalupe's feelings is that the lack of endorphins and her circumstances are causing depression. When people are physically active, their bodies release endorphins, which are chemicals that help improve mood and reduce feelings of pain and stress. Since Guadalupe is no longer able to participate in softball and attend softball camp, she is missing out on the endorphin release and the sense of accomplishment that comes from skill-building. This can lead to feelings of frustration and sadness.
