Abigail Deveraux has been one of the most beloved characters on “Days of Our Lives.”
Abigail has been through the wringer in the drama department, and it started from a young age.
As a baby, Abby was diagnosed with aplastic anemia and underwent a bone marrow transplant.

She also married her friend Dario Hernandez to keep him from being deported.
The two got married and welcomed two children together, Thomas and Charlotte.
The first she modeled after her former friend turned enemy Gabi Hernandez (Camila Banus), perSoap Dirt.

Abby’s alter-ego would dress like Gabi complete with dark wig.
Eventually, Abigail started showing another alternate personality.
This one was also modeled after someone in her life, her grandmother Dr. Laura Horton (viaSoaps).

Thankfully, Abigail was eventually given the help she needed, which included medication and therapy.
She later returned home and resumed her life with Chad and their children, perSoaps in Depth.
However, her mental illness still followed her around like a shadow that loomed over her life.
So, what exactly caused Abby’s alternate personality disorder?
Laura and her own mother both battled mental health issues, and Laura spent many years institutionalized.
Sadly, it seems that the family history of mental illness may have been passed down to Abigail.
Ben kidnapped a heavily pregnant Abby and held her prisoner at a remote cabin (viaSoap Central).
After Abigail gave birth, Ben took her son and left her to burn alive chained to the bed.
Thankfully, she was saved and eventually got her son back.
Abby was diagnosed with PTSD and treated.
However, her fragile mental state eventually caused her split personality disorder.
Sadly, Abigail’s story doesn’t have a happy ending.
