Should I be offended when my aunt said I look so big in my picture?

She noticed that I'm getting bigger in my legs and it isn't healthy. She flat out told me, "Why are you getting so big? What have you been eating. Tell me so I can help you." I was embarassed. I am 234lbs plus I'm 5'10. I've been trying to lose weight but it's so hard. I asked hee what she though about my picture. She said, "You look so big in this picture." I waz hoping she said I look beautiful. She said that I always look beautiful and she dont need to tell me that and she said I could lose some weight. I know I do but thwt hurts
