Answering for Darla!
Recent RP events have had her feeling like she only ever makes the Wrong choices, and she's hurting over the fact that she's (indirectly, unintentionally) hurt people she's cared about.

She's never had the best self-confidence due to her mostly-absent mother, her appearance, and some personal betrayals in her backstory. She struggles with self-worth, which is ironic given how much she stresses the importance and worth of everyone around her.

Darla believes people don't have to /earn/ basic dignity and respect, and that happiness and safety aren't things one needs to "deserve"... but she struggles to apply those principles to herself, often feeling like she doesn't deserve kindness and aid and comfort.

She struggles with the idea of being a burden on anyone, because she's so determined to not be more of a burden than she already thinks she is. She doesn't feel like she's on the same level as her loved ones, but she doesn't really see how much she's improved their lives just by being present. She refuses to see her own strengths.
