I've endured some pretty horrific events in my past, and I've had years of intensive trauma therapy as a result.
Several years ago, my lead trauma therapist asked me to come up with a protective figure. Basically, you try to "change" the end of your traumatic experiences in your mind, by having your protector saving you / comforting you / something similar.
I tried everything, and everyone, I could think of. Spiritual characters, cartoon characters, people I'd known. Absolutely nothing worked.
One day I was having a very torturous flashback and... there was Rapunzel, no idea why. It's really not something I want to talk about here, but Rapunzel has been my protective figure ever since. Rapunzel done more for me overnight than a decade of intensive therapy did.
