For example, I want to describe the “opposite of spoiled’ child who’s been beaten by their parents, never gets allowance or rewards or gifts even for hard work.
A few words that come to mind but don’t really fit perfectly: forlorn, deficient, inadequate, pitiable, paltry.
A sentence where this word would be used:
Person A: "You're a spoiled child with a nice house and relatively middle class."
Person B: "I might have many physical gifts, but I'm not spoiled emotionally. In fact, I'm a [insert word/neglected/doormat/scorned/ignored] child when it comes to love. My parents tell me I'm worthless, everything is my fault, I'm bad at everything I do, and that they wish they were dead because of me."
Person A: "Oh, I see... sorry for the judgment."
