He might focus on his training. By pouring his energy into getting stronger, he can distract himself from his lonely feelings. Naruto has always been determined, and training gives him a sense of purpose.
In the fanfiction, Naruto may find comfort in his memories of the few positive interactions he had. He could hold onto those memories of when Iruka - sensei recognized him, or when Sasuke showed a bit of friendship. He replays these moments in his head and uses them as a source of strength to endure his loneliness.
In many fanfictions, Naruto might start by training harder. He throws himself into his ninja training as a way to distract himself from the loneliness. It gives him a sense of purpose and also helps him become stronger.
His parents' death also contributed to his loneliness. Growing up without them, he didn't have that family support and love that most kids had. He had to fend for himself and deal with his feelings of abandonment all alone. And in the fanfiction, perhaps his friends are too busy with their own missions or problems, leaving him feeling isolated.
The fanfiction could explore Naruto's loneliness by depicting his isolation during his training. He often has to endure difficult and solitary training sessions. This physical and mental isolation can emphasize his loneliness. Also, in some fanfictions, his loneliness might be shown when he faces discrimination from the villagers. Despite his efforts to be friendly and gain acceptance, there are still those who shun him, which deepens his sense of being alone.
Naruto might cope by focusing on his goals. He's always been determined, so he could pour all his energy into achieving something in the modern world, like getting an education or mastering a new skill.
He might focus on his training more. By pouring all his energy into getting stronger, he can distract himself from the pain of family neglect. For example, he could spend long hours practicing new jutsu or improving his physical abilities.
Naruto might try to seek attention elsewhere. He could focus on his training more intently. By pouring his energy into becoming stronger, he distracts himself from the pain of parental neglect. Also, his friends could play a crucial role. Their friendship might give him the sense of family and belonging that he lacks at home.
He could also try to find a new family or group to belong to. Maybe he befriends some outcasts in the village and forms a new kind of family with them. This new support system helps him cope by providing love and acceptance that he was denied by his own clan. He would learn that family isn't always about blood relations.
He might initially feel a great deal of sadness and confusion. Naruto is a character who values friendship deeply, so being abandoned would be a huge blow. He could isolate himself for a while, reflecting on what went wrong. But Naruto also has a strong will, so eventually he might start to focus on self - improvement, training harder to prove his worth not just to his former friends but also to himself.
One common theme is self - discovery. Naruto's loneliness often makes him look inward and try to understand himself better. Another is the search for family. Since he lost his parents at a young age, his loneliness in the fanfiction can drive him to seek a sense of family, whether it's with his friends who become like family or through finding out more about his own heritage. Also, the theme of acceptance is common. His loneliness stems from not being fully accepted in the village, so fanfictions may focus on his journey towards total acceptance.
Naruto might throw himself into his ninja training. He's always been dedicated to getting stronger, and heartbreak could fuel that drive even more. For example, he could spend countless hours perfecting new jutsu or sparring with his friends. Another way he could cope is by relying on his friends. Sakura and Kakashi, for instance, could be there to support him, listen to him vent, and offer advice. He might also find solace in eating ramen at Ichiraku. The familiar taste and the warm atmosphere of the ramen shop could give him some comfort.
