I was told this early on and I'm not claiming it's easy to do. It's hard to put the focus on you and bootstrap yourself to a better place mentally.

You've made mistakes. That's how we learn. Own them. If she said something about your behaviour or your character that made you angry or you felt a 'sting' examine why. Is it just a little bit true?

It's your choice.
