Somewhat related, a psychologist I talked to in the 2000s said she really liked the Patronus concept in the Harry Potter books. You imagine an entity that's fueled by your positive memories and emotions, and that protects you from certain anxieties and other stressors.
Things like that seem to be used in at least some schools of psychology.
It reminds me on something my psychologist told me, when trying to find this me-mentor, it can help to take inspiration from someone I find really safe with and trust a lot. Aka someone I have good memories with / of.
