Lovebirdsflying, people can be so horrid to folks who are overweight. When I lived in southern california, two of my closest friends were big; one had had horrible back infuries, so her activity range was limited, plus she had been assaulted as a child. The other was the tiny one in her family! There were strong genetic faktors in her case that once you'd seen her extended tribe, you understood that this was not a simple "eat-less-excercise-more-issue". I was ammazed how man total strangers felt entitled to walk up to us and start comparing us (I am not obviously overweight and then I was even thinner)and making comments as if my firends had somehow insulted and offended these people.
I suspect that it is a bit of the "I am the master of my fate " mentality so common in our culture that leads to people assuming that if a solution is easy to say, then it is easy to do. The idea that, yes, IF my friend got a personal trainer (how much does THAT cost) completely stiffoperated her back (again, price, complications) and ate 300 calories a day, she might be able to lose weight, but in the end that would be limited by a host of other issues. Improvement is possible and reasonable to expect. Total reduction to normal weight is not, with her, or with my other friend.
You're not here to be a balm for their hypercritical eyes, dear. People have trouble realizing that we, especially women, don't have an entire life worrying about how we present ourselves to THEM. People who have those tendecies are bullys first, whoo have a tendecy to go after the weakest in society. In addition, there is this little narcisisstic idea that it is all about THEM, and of course you should be worried about htat they think, they are so important, and they don't like the way you look. The fact that you might just not care is like afrontal attack oh their being.
I wish I could tell you ignore them, but I know in the end it doesn't work. I am glad that one doctor is not likely to meet you again. H sounds like he should be kicked in the package (my son did that here to a man who imitated my accent while he was checking my son's ears. I had trouble not laughing, couldn't even scold the kid).
My heart goes out to you. Take care of yourself, and rember that the most valuable thing about you cannot be seen, only known. Huggs
