Do you think my aunt is being judgmental?

Sounds very bossy and controlling, I'm happy i don't have anyone like that in my family. A C is totally fine, you did good in other subjects. Maybe don't tell them as much and contact them less. Its unreasonable for her to want you to become a vegetarian. I have a few friends like you (picky eaters) I would never try to convert them to be a veggie like me lol
