His past traumas could resurface. For example, the memories of being shunned as a child in the village. If some event were to trigger those memories again, like a new wave of discrimination against Jinchuriki in the village, it could make him feel like he's back to being that lonely outcast, which could lead to severe depression.
In a fanfic, one possible cause could be the loss of his loved ones. If he were to lose Sasuke again, this time perhaps permanently, it could send him into a deep depression. He's always been so focused on bringing Sasuke back, and if that hope is completely dashed, it would be a huge blow.
One possible reason could be the loss of his friends. In the Naruto universe, his friends are his most precious. If he were to lose some of them in a really tragic way, like Sasuke turning truly evil and being killed while trying to destroy the village, it could plunge him into severe depression. Another reason might be the weight of his unfulfilled dreams. Naruto has always dreamed of a world of true peace, but if in fanfiction he constantly faces setbacks in achieving this, like new wars breaking out despite his efforts, it could lead to depression.
A plot could involve Bulma facing personal losses in her relationships. Maybe she has a falling - out with her friends or family, and this causes her to spiral into severe depression. She could then start to isolate herself from the people she loves, and the story could focus on her journey to recovery with the help of those who care about her.
Another aspect could be in his physical appearance and actions. He may lose his appetite, so he no longer enjoys his favorite ramen as much. He could also seem less energetic during training, often zoning out and being less focused than before. His eyes might lose their usual spark, always looking a bit dull and lifeless.
Iruka sensei, who has always been like a father figure to Naruto, could offer his unconditional love and support. He could share stories from Naruto's past, reminding him of how far he has come and how strong he is. Sasuke could also play a role. Despite their past differences, Sasuke could show Naruto that he's not alone in his struggles. They could train together and Sasuke could share his own experiences of dealing with inner demons, which might give Naruto some hope.
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, in New York, the Jewish guy could be depressed because of the urban environment itself. The noise, the crowds, and the general chaos can be mentally exhausting. Also, if he has experienced discrimination, whether it's related to his religion or not, it can really affect his mental state. And let's not forget about the economic factors. If he's in a financial bind, perhaps struggling to pay rent or afford other basic necessities while also trying to uphold his Jewish traditions which can sometimes be costly, it can lead to a downward spiral into depression.
One possible cause is the financial stress. New York is an expensive place to live, and if he's trying to support a family or just make ends meet, it can be really tough. Another reason could be the social pressure within the Jewish community itself. There might be expectations about how to observe traditions, which can be burdensome if he's not fully in line with them.
Another cause could be the pressure she feels to be a symbol of the rebellion. In fanfics, she might feel trapped by this role. She has to constantly uphold an image for the people, but inside she is just a broken girl. This disconnect between her public self and her true self can cause a great deal of inner conflict and ultimately depression.
One common cause is improper lifting. For example, if you lift a heavy object with your back instead of your legs, it can put a lot of strain on your back muscles and spine. Another cause is accidents like car crashes or falls. In car crashes, the sudden impact can cause the back to be jerked around violently. Falls from a height can also lead to serious back injuries.
