She isn't suicidal, but she feels she wouldn't regret it if her time came at any moment. She has never been loved or treated with kindness in her life and doesn't know human warmth. She decided to run away because she wanted to know what love is. The only time she has ever eaten warm food was at school. At home, she basically ate her mother's leftovers. She is allowed to go to school, but naturally finds no joy in it. She is neither liked nor disliked by her classmates.
