A bit ago I had an interesting conversation about giving names to the many characters that make up one's mental chatter.
I have a particularly unpleasant one I refer to as "The Mean B*tch". She is downright nasty and unpleasant and she shows up when I am already feeling defeated. All of her unhelpful perspective is directed inward. She's a combination of unpleasant emotions.
Maybe you have an envy character that shows up when you spend too much time comparing yourself to others and then make unrealistic expectations of yourself by projecting yourself into their circumstances.
There could be the failure character that takes every challenge as a failure and creates a dramatic story about how you can never succeed.
Or what about the procrastination character that creates stress surrounding your lack of initiative. There are likely seeds of accuracy, but the tone is not helpful and leads to more procrastination.
Then there's the anxiety character that says you suck at coping and you'll never be able to do anything calmly again.
The depression character says why try, nothing I do makes a real difference for myself or others.
You probably have a cocktail of your own characters. It could be helpful to notice the stories they create and that most likely they are broken records. Name them. Call them out. Listen to the underlying message. Find the nuggets of truth and then rework the story. The characters of not likely to go away entirely, but you will have more awareness of them and more success at not identifying 100% with them.
