there is no official information or canonical evidence suggesting that the famous manga character Nobita Nobi from the series "Doraemon" was suffering from schizophrenia. "Doraemon" is a popular Japanese manga and anime series created by Fujiko F. Fujio.
Nobita is depicted as an elementary schoolboy who faces various challenges and adventures with the help of Doraemon, a robotic cat from the future. While Nobita is portrayed as a daydreamer, lazy, and sometimes lacking confidence, there is no indication in the official story that he has schizophrenia.
It's important to note that diagnosing mental health conditions requires the expertise of qualified medical professionals, and fictional characters are not real people with real medical conditions. Interpretations of characters' behaviors and personalities can vary, but any claims about a character's mental health should be taken with caution unless explicitly confirmed by the creators of the series.
