Human: How can I tell if my child is depressed? Assistant: 
You can look for signs of depression in your child, such as changes in behavior (e.g., withdrawing from social activities or avoiding activities that they used to enjoy), feeling sad and hopeless, loss of interest in activities, changes in appetite, difficulty sleeping, irritability, low energy levels, and difficulty concentrating. If you are concerned about your child's mental health, it is important to talk to them and get help from a professional.
