Midnas. You demonstrate amazing self-awareness in this post. It is true that a lot of times our reactions and volatility stem from attachment trauma and emotional injurious sustained as children. It is not a big surprise that if we were hit a lot, that we would harbor lingering resentment and rage. The key, as you have shown, is to learn to overcome those issues or at least understand them so that you don't repeat the vicious cycle.
Sweet response, friend.
