I'm sorry to hear about your Dad! My whole family is over weight but I am the biggest. I weigh 454 now. I started at 484. I am still pre op. My mom has a lot of health issues due to her weight. She weighs about 360. She has diabetes, high blood pressure, back and knee problems. She is in denial. She's addicted to food and nothing can stop her from eating. At family get togethers she sneaks in the kitchen and eats. I have been on a diet for the last 6 weeks and I have been trying to get her to do things with me but she won't. I feel like I can not do anything to help her. I try to talk to her every time I see her but it goes in one ear and out the other. I'm stuck between a rock and a hard place with her. Maybe when I get my surgery she will see how well I am doing and she will start to help her self. At least that's what I'm hoping for!!
