MY HEALTH AND LIFE'S ISSUES

My seems to keep deteriorating.... BUT I don't seem to want to do anything about it.... Why? Because I seem to have this crazy idea that I am going to suffer the same fate as my fate as my Mother. She passed away 11 years ago at 66 years old from ALS or Lou Gehrig's Disease. Why do I think this? BECAUSE: Of all of her children, I am the MOST like her: I look like her - I am the only child who has her coloring - Blonde hair Hazel eyes. All of my siblings have dark hair and eyes. I am the same height as was: 5'4" I have the same weight issues she did: I am struggling with it. I have been depressed for most of my life; as was she. We both had difficult childhoods. Different reasons, same results. Her mother died at the age of 66 years, from complications resulting from obesity, heart issues, blood pressure issues and diabetes. I am obese, have diabetes, high cholesterol, depression, and thyroid issues. Her next oldest sister died due to complication with ALS....at the age of 66 years. So I figure that I have approximately 15 years of life left. I am 50 years old at this moment. So instead of fighting to get "well" I am curling into a ball, and slowly succumbing to my fate. Why though? I have two kids who need me....although I am sure that my husband could manage quite well without me.... I have never heard him say otherwise, so I assume that this is so. (I have told him on several occasions that I could never have accomplished what we have without him.) ? What is it gonna take to shake me out of this? I have already almost died once during a surgery.....does this need to happen again? Maybe if I remembered anything about the near death experience, it would make a difference.....maybe. WHAT DO I DO ????
