I dealt with them through either confrontation or avoidance, and that contradiction itself is one of my greatest insecurities. I want to be solid, well founded, and when I contradict myself I feel as though my identity isn't defined. Now that I am mentally healthier (if only slightly) I find it easier to mend these problems, but not solely for my own sake. How could I ask someone to do the same if I can't handle my own insecurities.
Realizing that insecurities are natural is a great way to be bolstered against them, and I admit I'm actually fond of discovering the reasons behind them. I know myself very well, and I find that to be my greatest asset. Sometimes there are so many questions raised that I am more indecisive than insecure, but after gaining more experience the decisiveness come more naturally. Perhaps it's the value driven thought process, and once the value is shown it becomes easy to react.
