What has happened to my sister?

[Eliana]

It sounds like your sister is going through some difficult things right now. She may be dealing with issues at school or socially. You should tell an adult (your parents? The school counsor?) that you trust about what's going on with your sister. It sounds like she needs help. its great that you are noticing changes in her character - you can get her the help she needs and could possibly save her from harm. I'm no wizard - I can't magically tell you what's wrong with a person I've never met, but I can tell you that as a carring sister and friend, you need to make sure that your sister stays OK. Better safe than sorry.
