It could be due to the trauma he has experienced. Losing friends and facing Voldemort multiple times has surely left deep scars. Isolating himself might be his way of dealing with the post - trauma stress. He needs time alone to heal and come to terms with everything that has happened.
Another reason could be that he feels different from others. Despite having friends, he is the 'Chosen One' and has unique powers and a special destiny. This sense of otherness might lead him to isolate himself as he may think that no one can truly understand what he is going through.
Perhaps he's dealing with some sort of trauma. For example, after the many battles he's been through, like the fight against Voldemort, he may be suffering from post - traumatic stress disorder. To cope with this, he isolates himself from others as he doesn't want to burden them or he's just too caught up in his own dark thoughts.
One reason could be the shock of the revelation. Harry has always thought his parents were James and Lily. Discovering Snape is his father would be a huge shock, and he might isolate himself to process this new information.
It could mean that he imposed his own ideas, writing style or plot twists onto a Harry Potter fanfiction in an overbearing way. For example, if someone is writing a fanfic and they force their own out - of - character interpretations of the characters or force a particular relationship that doesn't fit the spirit of the original series.
It could be that Harry reads Harry Potter fanfiction to feel more connected to his fans. By reading what they write, he gets a sense of how they view him and his friends. He might also find comfort in the fact that his story has inspired so many people to create their own tales within the same universe. Fanfiction can be a form of flattery, and Harry might enjoy seeing how much his story has captured the imaginations of others.
He might choose to obliviate himself because of guilt. For example, if he made a big mistake during a fight that led to the injury or death of an innocent, he couldn't live with the memory. So, obliviating himself would be a way to escape that emotional pain.
Well, for the Harry Potter fan community, it's a bit of a shocker. The community is used to the idea of Harry as a survivor and a fighter. Such a fanfiction can create a divide. Some might be intrigued by this very different take on the character, seeing it as an exploration of the extreme. But many would be put off because it doesn't align with the spirit of the books. It could also make some fans question the boundaries of fanfiction and what is acceptable within the community.
Well, he might manage his daily life by relying on magic for basic tasks like cooking. He could use spells to clean his place and keep it tidy. Maybe he'd also use magic to grow some food in his small garden if he has one.
On the other hand, it could also start some interesting discussions within the fandom. It might make fans think about the darker aspects of the wizarding world that were not fully explored in the original books. For example, how much pressure can a young wizard like Harry actually bear? However, it also has the potential to make some fans feel uncomfortable or even depressed, especially those who are more attached to the positive and heroic image of Harry.
In some fanfictions, Harry might use his quick thinking and knowledge of magic laws. He could present evidence clearly, like memories in a Pensieve to prove his innocence. For example, if wrongly accused of using dark magic, he could show how the situation was misinterpreted by bringing witnesses who saw the real events.
Because 'Harry Potter' is an original and highly creative work with its own unique world - building, characters, and storylines. It's not derivative fanfiction. J.K. Rowling created the entire wizarding world from scratch, including Hogwarts, the Ministry of Magic, and all the spells and magical creatures. It has a distinct identity and has been developed in a way that sets it far apart from being a simple fan - made addition to an existing 'Potter' concept.
