<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 has depression is by asking him questions about his mood and behavior. You may want to ask him how he's feeling, whether or not he's sleeping well, what activities he enjoys doing, and if he feels like he has a lot of energy or not. You can also look for signs such as changes in appetite, loss of interest in hobbies, difficulty concentrating, irritability, feelings of worthlessness or guilt, and thoughts of suicide or death. If you notice any of these signs, it could indicate that your son might have depression.
