My sister is 10 months younger than me but we are practically twins since we were in the same grade. We both deal with the stress in our life differently, I excersize a lot and can try to overly control things like how my rooms looks and stuff and she eats. Omg she eats all the time. Her room is full of junk food, she is crabby all the time, she got kicked off the cheer team cause she can't tumble anymore, her boyfriend broke up with her, all things I believe happened due to her gaining weight. She's 5"4' and close to 170 now. I have no idea how to help her. I know shaming isn't the answer but she doesn't seem to ever want to talk to me about it either. How do I encourage her toward positive change?
