What were some things that Adeline had to get through and how did she cope with in her life other than PLT and her being unwanted?

There are many things Adeline had to contend with. Isolation, self-worth, sadness.....Adeline is an outcast in the eyes of much of her own family, since her birth brought upon the death of her mother. Her inadvertent role in her mother's passing causes animosity between her and her older siblings and contributes to her father's apathy towards her. Adeline coped by throwing herself into her studies.
