I love defense mechanisms! I wouldn't be here without my wonderful ones. However, I don't need too hearty, over-developed defense mechanisms anymore but I wouldn't "get rid of" or substitute the ones I have for others, what's the point? What I learned and how I deployed my defenses is unique to me and served me well growing up and that makes them easy to use when I do in fact need them, even now. But now I'm aware of what I have and how I use them and can "deploy" them better when they're appropriate and can help me.
