(((Cheesy))), I know the less people who know the better however it sounds like your Sister is trying to show you that she cares about you and is in your side. She is saying things that she thinks you want to hear and will make you feel better.
Off course she is speculating and mind reading so anything she said you should just take with a pinch off salt and maybe change the subject in future. Nothing has changed because if what she has said.
You are doing great!
