I made a comedy sketch about being dramatic because it reflects a lot of what I've seen and even my own attitude.
Basically, folks will be told they suck, or that they're ugly or that they're not funny etc. and in response they'll blame everyone but themselves... I have done this in the past too... thought "Oh, criticism, must be false and they're just a jerk." when in reality, there was a reason for the criticism, valid or not, there was a purpose. When you blame other people for the way you feel, you admit you do not control how you feel, that you do not have power over yourself as much as many others do, and you gave all your power to someone else. Kinda deep for a dumb little comedy sketch huh?
