In the 'Harry Potter lost the will to live fanfiction', it could be due to a sense of futility. If he's constantly fighting against dark forces but seeing no real, long - term change in the wizarding world. For example, if new dark wizards keep emerging despite his efforts, he may feel like his struggle is pointless. Also, if he discovers some dark secrets about the wizarding world or his own past that shatter his beliefs, that could lead to his loss of will to live.
One possible reason could be the continuous loss of his loved ones. In the original series, Harry has already endured so much pain from losing Sirius, Dumbledore, etc. In the fanfiction, perhaps there are additional deaths or betrayals that push him over the edge. Another reason might be the overwhelming burden of being 'the Chosen One'. The constant expectation to save the wizarding world could finally break him.
One possible reason could be the overwhelming burden of his destiny. Constantly facing dark forces and the pressure of saving the wizarding world might have worn him down. Another reason could be the loss of his loved ones. For example, if in the fanfiction Hermione or Ron were killed, that could shatter his spirit.
Maybe he was hit by a powerful dark magic spell specifically designed to target the soul. Such spells in the Harry Potter universe can be extremely dangerous.
In the fanfiction, Harry Potter might live by himself because he is tired of the spotlight. After being in the public eye for so long, he desires a private life. He may also feel that living alone allows him to better understand himself and his powers. It could be that he has a prophecy or a personal quest that requires solitude. For example, he might be trying to master a very difficult and dangerous spell that he doesn't want anyone else to be in danger from if something goes wrong. Also, he could be exploring some dark corners of magic that the wizarding world might not approve of, and living alone gives him the freedom to do so without judgment.
One possible reason could be the excessive burden of his destiny. In fanfiction, he might feel constantly pressured by his role as 'the Chosen One'. The never - ending battles and the loss of his loved ones could also contribute. For example, if he loses Hermione or Ron, it could shatter his will to keep going.
One reason could be the extreme hardships the characters face in the original story. For example, Harry has lost his parents, faced Voldemort numerous times, and seen many friends die. In fanfiction, this could be amplified to a point where a character feels they have no will to live. Another aspect could be related to the sense of isolation. Some characters, like Snape, were always sort of alone in their struggles, and in fanfiction, this could lead to a loss of the will to live.
One reason could be that Harry wants to preserve the integrity of his real story. Fanfiction often takes the original story in different and sometimes wild directions. He might worry that it could distort the truth about his adventures, his friends, and the sacrifices made. For example, some fanfictions might create romantic relationships that didn't exist or change the motives of characters, which could mislead those who are new to the real story of Hogwarts and his battles against Voldemort.
Perhaps he is betrayed by those he trusts. In the original series, there were instances of betrayal, and if in the fanfiction this is amplified, for example, if the whole wizarding community turns against him unjustly. He might feel so alone and hopeless that he loses his will to live. Also, if he discovers some dark secrets about his past that make him question his own identity and worth, it could lead to this state.
The story could develop with Harry's friends trying to bring him back from the brink. They might search for a way to reverse whatever has made him lose his will to live. For example, if it's a curse, they could look for a counter - curse. Another way could be that Harry has a moment of self - realization and decides to fight back against the despair. Maybe he has a vision or a talk with a ghost from his past that gives him a new perspective.
In fanfiction, Harry could flee Britain due to a sense of disillusionment with the wizarding world there. He has been through so much trauma and has seen the flaws in the system. For example, the way the Ministry handled the threat of Voldemort in the past was often inept. He might also be seeking a place where he can explore magic in a different way, free from the traditional constraints of the British wizarding community. He may want to start anew in a place where no one knows him as 'The Boy Who Lived' and can just be Harry, an ordinary wizard exploring his magical abilities.
One possible reason could be a fallout with his friends in Gryffindor. Maybe he feels betrayed by them in some way in the fanfiction world. For example, if they wrongly suspect him of something.
