Kids get depressed, just like adults. It’s something, as a parent, you need to be aware of and look out for. A depressed teen does not have the wherewithal, generally, to come to you for help, especially when one of the symptoms is isolation. If you’re waiting for your teen to come to you, you’re going to be waiting a long time, maybe too long. So you need to be proactive. Know the signs. Even though all kids are different, there are some specific things to look for, according to the National Institutes of Health’s National Youth Violence Prevention Resource Center (that’s quite a mouthful, but, luckily, the website is a bit shorter—SafeYouth.gov). No one of these signs is a definitive red flag that says, “Yes, your teen is depressed.” Rather, they form a pattern of concern. They should catch your attention and slow you down long enough to investigate the source of the smoke, even if you have trouble catching it in your hand.
