heat

Hello everyone I am 27 years old have five small children aged 7,6,5,4,2 and I am 248 pounds when I should only weigh about 135. I have had a brother and a father die from heart failure because they were over weight. I do not have high blood pressure or any of that however my weight restricts me from doing things. I can not go to the park and enjoy myself with my children because I get tired all the time and get depressed when I see myself because this isn't the way I wanted to be.
