Firstly, I would like to point out that your name is just awesome. "Chels at the disco"
Secondly, I'm not going to give you a modest, and overplayed answer by saying that I'm here to help people, because I am, really, I do want to help, but I think that my primary motivation is that I find it to be interesting, I can help others while curing my interest in some of these theories, psychology has always been a major interest of mine and the fear that these theories put into people is nothing short of staggering, it's absolutely intriguing to someone like me, but I will never let my interest get in the way of my judgment when it comes to giving someone advice of how to get over their fears.
So, that's pretty much it, for me.
