The worst depression always strikes, after you have a normal calm and happy day with a friend, and suddenly your brain realizes, that this ammount of insane hapyness you feel twice per year is actually supposed to be the norm.
@LukeAlmighty I don't think that's true tbough. The natural state of man is abject poverty and always fearing death. Capitalism is a lie, don't let them tell you that you're not normal.
