Me-N-Mine and Blue Phoenix both gave great advice. Depression usually results of loneliness + idleness. You'd be surprised about how many people around you actually feel this way, if not worse. Fake smiles are a thing. And I have to disagree with BP about lying to yourself, the truth always surfaces sooner or later. Don't run away from it, face it head-on. Learn to accept it and deal with it. It will make you stronger. The world isn't perfect, there is a lot of bad in it. But there is also good, and it is beautiful, that is what we should fight to protect. Telling people to "pull your sh*t together" doesn't work unfortunately, otherwise doctors wouldn't be necessary. But you might be able to overcome it by yourself, and that would be great.
I like Tales from Earthsea.
