I have a new colleague at work who is about seven years younger than me and has been trying to advise me on my Ulcerative Colitis. She’s been saying I need to eat more, have breakfast (because it’s “the most important meal of the day”), have more fruit and veg (despite me telling her it’s bad for me when I’m flaring) and she has even said once that she think it’s “all in my head” and that I need to “think positively” to feel better. I want to tell her in the nicest way to back off but I don’t know how. I don’t want to get my manager involved but I can’t let my colleague keep thinking my UC is an open topic. She’s even said she wishes she could be like me and “not eat” so she could be skinny. It makes me kind of angry and annoyed that she thinks like this. I want to say something to put her straight but I don’t want to make thinks awkward at work. Our store is tiny so it’s not like I can avoid her.
Any ideas of how to approach this are welcome!
