I don't know where the word "depression" came from, it just cropped up overnight. It started in the 90's by the drug driven media industry, it was a replacement for "sad". They noticed "sad" was too regular a word so they invented "depression". Now, stupid people everywhere are running to the doctors to treat their depression. Tell me, if you are happy forever, does that do anybody any good? Yes, we feel pain, thats part of the life. Pain is a result of our ultra sensitive nervous system, which tells us when something is going on, like when your 2 year old little brother stabs you on the feet with a sharp pencil. Without this mechanism, we wouldn't be able to feel, which would be a lot worse than...(chuckes)...being sad. Ever seen the movie "equilibrium"? My advice? Shit happens!
