Fed up of comments from people saying I look huge, really big, massive why has pregnancy become all about what you weigh?

Andrea • This is my third pregnancy with severe hyperemersis! I'm looking forward to not throwing up every single day!!!!
I have put on 21lbs at nearly 27 weeks but I was petite before the pregnancy I'm eating well not badly and walk an hour every day yet all I am getting is criticism from family especially my mother is anyone else feeling like they just don't want to eat? All I've eaten today is museli and some rocket with a tiny bit of chicken :(
