Insecurities

I know that sometimes I can be quite the contradictory person. At times I become trapped in my own insecurities, whether it be long or short periods of time. I hate doing it. I hate having a mindset full of thoughts of being worthless, useless, that I'm just not good enough. I'm a thinker, and an over thinker to be honest. I think about what I look like, do I look pretty enough? I think about what I wear, am I going to be judged? I think about what I say, am I a bore? I comprehend and become lost in thought and too much of this makes it harder for me to escape. They eat me, and yet I act as if I don't care, but really, insecurities will never leave.
