No problem says Reddit! These depressed and lonely teenagers have looked deep within themselves and know who they truly are. Sure, teenagers have been making bad decisions based on emotions and peer influence for all of recorded human history, but these teenagers are special, and so anyone who questions their emotions is a hater and a bigot.

But, to answer your question, if a condition like bipolar increases by thousands of percent, you still don't give them medications and surgery that are not backed by rigorous research, especially when there's massive negative side affects.
