Just wanted to jump in and and offer support too. I'm waiting to be banded and am debating if I should tell my generally negative family. One thing I've learned is that it's almost impossible to change someone else's behavior or way of thinking, so the best thing you can do is change your response to it -- which in your case could mean ending the call as soon as they start in on what makes you feel uncomfortable or bad. Or you can get mad and set them straight. Or you can avoid talking to them until they are willing to really try to listen, understand and be supportive.
I had to take a 2-year bread from talking to my sister because she brought me down or tried to manipulate me all the time. Like someone else said, I felt happier and more balanced during that time. Be proud of yourself and what you know is right for your health and your children.
The results will speak for themselves! Good luck!!
