Well, it could be about Percy being in a very stressful situation like facing a powerful enemy he's not sure he can defeat. This causes him to have a panic attack. Maybe he starts hyperventilating and his friends have to come to his rescue and calm him down.
One possible trigger could be academic pressure. Maybe Percy has a big test or a difficult assignment that he feels unprepared for. Another trigger might be social situations, like being bullied or feeling left out by classmates. It could also be related to a specific location in the school, such as a crowded hallway or a particular classroom where something bad happened before.
Obviously, Percy would be the main character as it's about him having a panic attack. His friends like Annabeth and Grover could also be important characters. Annabeth might be the one who tries to use her intelligence to figure out what's wrong with Percy and how to help him. Grover could use his empathetic nature to comfort Percy during the panic attack.
Annabeth would be a likely helper. She's very perceptive and has been through a lot with Percy. She would probably be able to sense something was wrong and offer her calm and rational presence to help him through it. Grover could also be there. He's Percy's loyal friend and his empathy for Percy's situation would make him a great support. He might even use his nature - related powers to create a more soothing environment for Percy.
One possible fanfiction could be Percy having a panic attack during a battle. Maybe he's facing a new and extremely powerful monster that reminds him of past traumas. He starts to hyperventilate, his hands shaking as he tries to grip his sword. His friends notice but are momentarily too occupied to fully assist him, adding to his sense of isolation and fear.
One common theme is friendship. His friends often play a crucial role in helping Percy through his panic attacks, showing the importance of support systems.
One aspect to consider in this fanfiction is the setting. If it's set at Hogwarts, the familiar yet often stressful environment can enhance the panic. The old corridors and the constant presence of peers and professors can all contribute to Draco's sense of unease.
Friends could help Percy by distracting him. For example, they could tell a funny story or joke to take his mind off the panic. They might also encourage him to engage in relaxation techniques, like deep breathing exercises together. If they know what triggers his panic attacks, they could try to shield him from those situations, like if it's a certain person, they could keep that person away from Percy.
In such a fanfiction, the author may describe Draco's physical symptoms during the panic attack vividly. For example, his rapid breathing, trembling hands, and the feeling of being trapped. It might also focus on how his friends or even enemies react to his vulnerable state, which can add more depth to the story.
In this fanfiction, Naruto's panic attack might be caused by the pressure he feels. He has so many responsibilities, like protecting the village and his friends. Yamato might be a trigger because Naruto doesn't want to show weakness in front of him, but the stress gets to be too much.
