1.) "Her parents died when she was young and she has been on her own ever since. Whenever she meets someone, she blocks them out..." From these sentences, I can infer that she is depressed based on how she doesn't want to meet anyone.
2.) "She's cheated, lied, and maybe even killed to get the things she wants." From this sentence, I can infer that she gets everything she wants, based on her attitude.
