Delia was an adopted child to a caring Gardevoir mother. Her real parents might of left her or weren't able to take care of her, and so it was passed on to the Gardevoir. Her life was normal in till middle school came by. She was bullied many times because of her appearance. Delia was also teased many times and was sometimes beaten up somewhere privately. She didn't tell her mother about this, or she will even get hurt even more. Delia had nobody to stand up for her, therefore she had no friends either.
By the time she came to high school, she developed a crush on one of the popular boys. Delia had once tried to have his attention towards her, but all of them failed. Once again, she was bullied multiple times and it felt like middle school all over. A group of girls made fun of her when they found about her crush and that made the duskull give up hope. She was just a useless pokemon.
Serveral days have past and her mother was suspicious about Delia's behavior. She had lock herself in her room with the light off and had continue doing everyday. She denied to go to school in till it was heard that a disease has spread in the world, although her mother said it may have only because a common sickness. A few days past as school closed because of the disease, Delia left her room to tell her mother the truth, but the Gardevoir was nowhere to be found in the house.
The duskull was now separated from her own mother and later joined the Meds, that's what she thought to call them, as a Medic to help others who are hurt or in pain.
