Ok . So i had a friend who i thought she was my real friend genuinely but i found out that she talks badly about me, about my face, about my house, called me and my family ugly, she never heard about my stuff but always made me hear hers, i went to the mall with her because she was sad bc of a boy, then i dropped her off at her house, but she was saying to another person that my car is old, and said that im poor, and made fun of my house. Now that I stopped being her friend, stopped talking to her without explaining myself to her, i found out she still talks bad about me and says that I'm weird and crazy, and keeps lurking at my Twitter. What should I do or think? I feel very sad because I really liked her but the things she did and said really hurted my feelings!
