Feel like I need to move house

So I've lived in a small town for a year and half now, the house next door to mine went up for rent an we got new neighbours but unfortunately I know the people. When I was in school I got bullied and abused by the women's daughter, pulling down my skirt to make a fool out of me. I put that all behind me but now knowing they are living next door to me in this town just brings back bad memories. I don't wanna bring my baby up round horrible people and I don't wanna feel I'm always looking over my shoulder all the time. It's awful how something from the past still has such an impact on you
