Let her know that people who tease others because of ridiculous things like getting help (She is getting help for her feet and legs) are not nice people. They probably just want attention or to look better. But they are really putting themselves down in life. I wish you both luck and remember at least there is a treatment out there to help!!

Once when I was young i had an orthopedic problem and it was fixed after wearing and brace in my shoe and plenty of PT. I am basiclly all better now!
