My parents live in a different country; I get to see them once or twice a year. They are visiting me lately, and they will stay over for a month or so. My mom is a little bit sick and has to take medicine after every meal for the rest of her life.
It's not dangerous to her life if she keeps taking her medicine and eating healthy, but lately, she eats everything and has gained a lot of weight. It's really not good for her.
I love my mom, she is a wonderful person, and seeing her like this breaks my heart. I don't want her to get more sick and I'm very very scared of losing her because of that. I can't imagine my life without her. I want to tell her that I'm scared for her health and that she should eat healthy and that she should respect her diet, but I don't know how to tell her that.
I know that she is a sensitive person, she will not show that she's hurt even if she is and I really don't want to hurt her. How can I tell her what I described above without hurting her feelings?
EDIT : as mentioned in the question, I don't want to tell and control what what she eats, and even if I do, I won't be around her for a long time to do that, the question is: How to try to convince her to stick to her diet without hurting her feelings?
