Have a dialogue with yourself. Talk back if you find yourself sunk in a negative story. Create a positive to balance the negative rather than trying to defeat it.
Remind yourself that you are great, everyone has personality quirks, and you are loveable.
Talk to your inner child or fearful self. Remind it that you are capable and can get help from others.
Address judgments and blame. Blame is a spiral of thoughts that perpetuates ongoing anger and frustration. Since you can't change others, focus on changing your own point of view. Ask yourself questions to determine if blame is a distracting story of your mind. These questions, based on the work of Byron Katie, are detailed in chapter 4.
