Is this depression or anxiety or just normal for a teenager?

This is how I've been feeling a lot of the time too. I think sometimes us teenagers are unhappy with our lives. It's like we need something more to live for. I hope it's just a stage that we go through. Personally, I think you shouldn't go see a psychologist because they most likely won't understand what you are feeling. I've tried before. But we've just got to keep pressing on.
