I have family like that too. Thankfully I don't see them much. My immediate family, husband, parents, and sister are very supportive. I don't know why people are the way they are. We can't change them we just have to learn to let it go. The thing I laugh at most is my family who are "dieting", I giggle every time I talk to them. They don't get that you have to change your life. While I am enjoying cake they are hungry and jealous. Don't let them get you down, keep up your great work.
