Depression is chemical and only a psychiatrist can really diagnose it. Your school has one. It's quite common - don't be embarrassed. To help your friend, get her to see her attitude as a problem that is stopping her from getting what she wants in life. Don't give in to lethargy. Make yourself get up & do something & it generates energy & you'll be glad you did.
