<human>: I, 23f, have struggled with my weight since the 10th grade. And have recently found out that I have a condition that makes it difficult to lose weight as well as have children. 

My eight cousins (m and f ranging from 24-17) are all super fit and super thin. Weight has never been an issue for them. 

Since I was 18 my grandfather has made comments about my weight. Usually in greetings. (He's also spoken poorly of my ex even though we broke up months ago. But that's a different story. ) Usually something along the lines of "look how big you are!" (Referring to my weight since I haven't grown an inch since I was 12.) or "there's so much of you!" As he hugs me. 

This only happens to me. Not any of my cousins. As far as I know they've heard nothing but praise and kind words from him. 

I told my mom (it's her dad) and she just shrugged and said that she can't control what people say. 

I tried to shrug it off and move on. However, today my best friend and I drove 7 hours to go to my families anual camping trip. This time, he hugged my best friend after me and whispered in her ear that he liked hugging her better because he could actually get his arms around her. And then proceeded to use arm gestures to prove his point. He noticed me looking and told me it was nothing to concern myself with. 

I asked my friend and she confirmed what he had said. 

I told my mom and once again she just shrugged. 

I feel really alone in this. These comments really bother me. I'm close with a few of my cousins but I don't know if I should tell them or keep this to myself. Am I over reacting?

Can you give me a shortened version of the text?
<bot>: grandfather is being a dick about my weight. I don't have any support from my mother. Am I over reacting?
