People have posted about her weight

I'm getting very upset reading all of these hurtful comments towards this girl. Saying someone is too skinny is just as hurtful as saying someone is too fat. How do they know she isn't just naturally thin and has trouble gaining weight? I can't even with these people.

Her legs are normal thin indeed, but her arms are stick thin though.
But her face is so creepy, that's unhealthy skinny! You can actually see her tissue right through her skin, that is not normal!
And her always sad expression (unless when she speaks) is also quite disturbing. Her eyebrows move to normal when she speaks, but go to 'sad' when she doesn't.

It really is ridiculous. At her age I was 115 lbs and I am 5'10. I ate like crap, never drank water. Dr Pepper and chips all the live long day. I'd kill to have that metabolism back!
Everyone's an expert, right? ?

I was 115 at 5'11" into my thirties and only changed after I had kids. Worked out and gained muscle. Coca Cola and Reese Cups were my diet. Now it's coffee and donuts lol!

It doesn't matter if it's "hurtful" or not if it's unhealthy. Look I'm a tad overweight, but when my doctor told me it wasn't hurtful. They are trying to help out of fear for your well being.
