Ok, I want to make something clear as we progress with the story.
Zadie has a mental condition called Dissociative Identity Disorder a.k.a DID. It used to be called multiple personality disorder but they changed the name. DID is usually a result of childhood trauma and it is a way to help avoid bad memories.
Dissociative identity disorder is characterized by the presence of two or more distinct personality identities. Each may have a unique name, personal history, and characteristics.
This is not something that can be cured.
For more information about this disorder, you can watch a youtube called DissociaDID. She has DID and dedicates all her videos to educate people about it.
I just want you to know that I don't mean to offend anyone when writing about DID. If I get anything wrong please tell me and I will change it, if anything offends you tell me and I will change it or just erase it.
Thank you,
BYEEE
