The quickest and most effective way to step out of the victim space is to realise that you are not a victim at all. It is to see that you are in fact the persecutor. It's not the words said against you that has caused the most pain, it is only the ones you've agreed with. The battle has always been with your own option of yourself. You are the one who created the insecurity, and therefore you are the only one who can change it.
