Can broken really be fixed

You come from a prestigious family, you are a gentle kind-hearted person, but because of your sister you are seeing as a troublemaker, every time she does something bad, she always blames on you and your parents always believe her. you were sent to a reform school, you were there for 2 years and when you came back you were completely different, you were quiet and withdrawn, you obeyed without hesitation or question, you only spoke when spoken to and you never looked anyone in the eye, you flunched when people got too close or when being touched, you flinched at stern voices or raised voices
