I got sadness lost of appetite because i miss my best friend am i depressed?. because i got loss of appetite and i am sad often.

Not automatically: One can have loss of appetite and sadness when grieving an important loss -- these symptoms don't automatically mean depression. However, you've asked about this twice today so far. Because of that, i suggest consulting with a psychiatrist or other mental health professional to evaluate your complete situation. Hoping you've already seen your primary care doctor for a general health review too.
