I'm a sophomore, and I have a big sister. she's 25, but refuses to talk to me, and has this b!tchy attitude towards me. To make it short, she hates me and doesn't want me in her life. This makes me really sad/ frustrated. There's this senior girl at my school, and I look up to her very much. She calls me "lil sis" and i call her "big sis", and she's always there for me, unlike my real sister. We also are on the same team and have a lot in commmon, it's almost coincidential that we are so alike. but Is it weird that I call her my big sister? and is it normal to be Wanting to find a big sister because of how my real sister treated me?
