It could also be related to his unfulfilled dreams. Naruto has big dreams for the village and for peace. But as he progresses, he might realize that achieving true peace is far more difficult than he thought. The gap between his ideals and the reality might be leading to his secret depression.
One possible reason could be the weight of his past. Naruto grew up as an orphan, constantly shunned by the villagers. In the fanfiction, this feeling of isolation might be intensified, making him constantly depressed. Another reason could be the pressure of his goals. He aims to become Hokage but might face numerous setbacks that make him feel inadequate and depressed.
One possible reason could be unrequited love. If in the fanfiction, Sakura continuously rejects Naruto or shows no interest in him, it can lead to his depression. Naruto has deep feelings for Sakura for a long time, and constant rejection can be soul - crushing.
One reason could be that Gaara, being a powerful and complex character, might have a different view on the concept of friendship. If he were to tell Naruto that his friends are only with him out of obligation or because of his status as a hero, Naruto might start to doubt his relationships and become depressed.
There are several potential reasons. It could be a result of a psychological experiment gone wrong. Some fanfictions like to play with the idea of Naruto being a test subject, and this could lead to his emotions being numbed. Another aspect could be related to his role as a leader. In some fanfictions, to be a strong and effective leader, he might believe he has to hide his emotions. Additionally, it could be a reaction to the expectations of others. If everyone expects him to be a fearless hero all the time, he might start to suppress his true emotions to meet those expectations.
Well, Naruto has always been there for Sasuke in the original story. In fanfiction, Fem Sasuke might secretly like Naruto because she sees his loyalty. He's constantly trying to bring Sasuke back to the right path. This loyalty could translate into a deeper affection in the fan - created stories.
In fanfiction, Naruto could be depressed after the war because he realizes that the world he fought for is still full of problems. The shinobi system might still be corrupt in some ways, and he may feel that all his efforts haven't really changed the fundamental issues. He might also be suffering from post - war stress disorder, constantly reliving the battles and the horrors he witnessed.
One possible reason could be the intense and often dark nature of Anbu missions. Naruto might be exposed to a lot of death and destruction, which could lead to his depression. For example, he could witness the killing of innocent people during a mission and feel powerless to stop it.
One reason could be to protect someone. For example, if there is a threat against a friend or a loved one, she might meet someone secretly to plan a way to keep that person safe without alerting the enemy. It's a common plot in fanfictions where the characters have to be sneaky to outwit their foes.
One possible cause could be the loss of a loved one. In many stories, this kind of trauma can lead to depression. Percy might be struggling to come to terms with the death or departure of someone close to him.
Well, it could be due to the weight of expectations. Naruto is often seen as the 'chosen one' type of character. In fanfic, Sasuke might feel pressured by this. He might think that no matter what he does, he'll always be in Naruto's shadow. Also, their different upbringings play a role. Naruto grew up alone but with a positive attitude, while Sasuke had a tragic family past. In fanfic, seeing Naruto's strength despite his hardships could make Sasuke question his own strength and lead to depression.
