I am impenetrable.
I am impenetrable because I will it to be so.
I have the last say and I will not let you dig under my skin and I will not let you manipulate me and I will not allow you to have any power or sway over me. I have the agency in this situation. I decide what happens to me and how I react and I am telling you right now, you will not pierce me. You will not make me fall, because I am wrapped in an armor of my own conviction.
I am strong even though I have not been in the past. I am fierce now and nothing you say or do will change the fact that I have chosen to fight for myself first.
I am impenetrable because I am free.
