Mary's mother never wanted to see her because she thought of her as an ugly and sickly child. I think this hurt Mary badly and she is mean because she hasn't been shown kindness but the person who should be close to her. She was taken care of by servants instead of her mom. If Mary had been shown some compassion, she could've turned out differently.
If your narrative discusses a challenge that you overcame, it would be best to use a first-person point of view. This is because it makes the writing seem more personal.
