When I was a child, my favorite books were probably Dorrie the Witch. (or among them), by Patricia Coombs. Edward Gorey had some nice hatching, but I didn’t relate to the characters. The Dorrie illustration style was similar, but I understand why I loved the art and the protagonist. (more below). This character always calmed me down/cheered me up when I felt gloomy.
Dorrie is a child who was a bit depressed. (that was me) and has high anxiety, is messy and timid. (same)
She is an only child and a bit lonely. (I even also had a cat).
She has a close relationship with her mother but a nonexistent/absent father.
Dorrie is surrounded by some hierarchy and some oppressive (and sometimes abusive) adults but her mother is good. Her mother is a grown up version of her. Thus, there is some hope in her world.
Despite her melancholy and timidity, Dorrie somehow comes out of oppressive situations and is the vainqeuer (victor).
Dorrie is an individualist and free thinker.
