If picturing your younger self is still hard to do, it may be helpful to think of this voice as an animal or a character of some sort. For whatever reason, the image that comes to mind for me is Totoro from the film My Neighbor Totoro, who is an adorable woodland creature with tall ears, wide eyes, and a squishy belly. When you can picture this scared voice coming from a being separate from you, whether it’s a younger version of you or a fictional character, it will be easier to remember that those thoughts are not you, that you are the one listening.
