Fatphobic 4th of July with family

Sorry, this is gonna be a long one. I have to let it all out.

This 4th of July I had to spend with my grandparents and my mom. So we went out to dinner that evening. I thought it would be nice to be out enjoying the nice day. Anyway, the entire time, my grandmother kept focusing on my weight while I was eating stating that I was losing weight or some bullshit. I explained to her that I was not dieting and do not care to diet because they don’t work. She just kept focusing on my size the entire dinner. I felt so uncomfortable about it. It just made me so angry because instead of at least asking about other things in my life. The only thing she cares about is my weight. I love my granny, but she is a pain to deal with sometimes. She is obsessed with weight, I mean OBSESSED to the point that she says she needs to diet and only wants to eat grapefruit because she wants to stay thin. She is freakin 80 years old. Why is she so concerned about staying thin instead of worrying about other things? I just dont get it.

Later that night, she asked my mom what we eat and stuff and my mom said that we ate a burger the other day. My granny was like “you don’t need to feed her a burger ever. That is the wrong thing to be giving her!” Basically, because I am fat, I am not supposed to eat what is seen as unhealthy food, but they eat the SAME foods all the time. I am fucking 26 years old and do not need someone to tell me how to eat for my damn body. I know how to properly feed myself, I dont need a teacher. People seem to think that fat people are stupid and dont know how to take care of ourselves. I hate to say this, but I am sick and fucking tired of people concern trolling me and thinking that I want to be thin and that I should be thin.

The whole entire day was a mess because she constantly keeps focusing on my food intake and what I eat and how much I eat. Then she keeps talking about my body all the fucking time saying that my legs are big and how she has thin skinny legs. I feel like a fucking joke because she just thinks talking about me is alright. I have told her numerous times that I dont like the way she is treating me, but she says “I’m being too sensitive and that she didnt mean it.” I hate fucking thin privilege and I am really angry right now, because I want to be treated as a person not a caricature of stereotypes that people associate with us. I want to be HUMAN! I want to be real and I want to be treated like a person!!!! Is it that hard for people to understand? Even family members?
