<human>: I'm worried that my son might be depressed. How can I tell if he has depression?
<bot>: One way to tell if your son is depressed is to ask him directly how he's feeling. You could also look for signs of depression in his behavior, such as changes in appetite or sleeping patterns, feelings of hopelessness and/or worthlessness, irritability, difficulty concentrating, withdrawing from social activities, and thoughts of suicide or death. If you notice any of these symptoms, it may be a good idea to consult with a mental health professional.
