For context, I (20F) study abroad far away from family. Because of everything going on, I came back home and was shocked to see my little sister (17F) has gained so. much. weight. It broke my heart, she looks completely different. To give you a picture, she’s 5’0 and has easily gained at least 80lbs and is now obese. If nothing is done ASAP, at this rate she will be excessively obese in no time.
I am aware this is the result of many factors and is a sign she has an eating disorder probably stemmed from anxiety.
My problem is that it’s difficult to talk to her about it. I haven’t tried talking to her but my other sister (18F) has been trying and she did not take it well. My sister brought it up in a way that “we should both lose weight and go to the gym together to motivate each other”. Did not go well. She cried and called her rude and insensitive and got even worse.
I’m working on finding a therapist (online) to navigate any underlying issues she has.
But my question is, how can I, as their eldest, be of any help in this situation? I obviously know she is sensitive and insecure about it, and my intention is not at all to make her feel bad. I just want to help her get in control before it gets worse, for her own sake. How do I bring it up elegantly so she can at least start taking control while taking therapy sessions?
Edit: I do want to add that I am not body shaming her. I love her and I know she isn’t happy with how she looks. But we can’t pretend that there isn’t a problem and underlying issues here that I, as her older sister, should be concerned about. I can’t possibly ignore this in the name of body positivity. At this rate, it’s just going to get worse and worse.
