Myth: Teens who claim to be depressed are weak and just need to pull themselves together. There’s nothing anyone else can do to help.
FACT: Depression is not a weakness, but a serious health disorder. Both young people and adults who are depressed need professional treatment. A trained therapist or counselor can help them learn more positive ways to think about themselves, change behavior, cope with problems, or handle relationships. A physician can prescribe medications to help relieve the symptoms of depression. For many people, a combination of psychotherapy and medication is beneficial.
Myth: Telling an adult that a friend might be depressed is betraying a trust. If someone wants help, he or she will get it.

Myth: Talking about depression only makes it worse.
FACT: Talking through feelings with a good friend is often a helpful first step. Friendship, concern, and support can provide the encouragement to talk to a parent or other trusted adult about getting evaluated for depression.
