Sick of my crazy AF sister

Katherine Kat,

Ok to make a long story short my sister has treated me like shit since I was small. She's 10 years older. Anyway she had a brain tumor at 19 and to have it removed . she now has to take a bunch of pills. Her moods change like the wind. It's not cause of her tumor she had cause she can turn it off and on . Anyway she had a baby with a guy she was sort of seeing. I love the baby she had very much but she uses him to get our dad to do things. Today she was griping about how she won't be able to get food. I think she's trying to get our dad to let her move back. I've got PTSD from the crap she's done in the past. My boyfriend said I could come live with him if it got too bad but I can't leave dad to deal with her plus he's got a Hart issue. Anyway I'm just venting cause I need get this off my chest.
