My fiancé just called off our wedding he is a diabetic gets itself insulin shots and was told that he had to now get an insulin pump we ve been dealing with it but what he didn t tell me is that at the same time they were doing test they also found out that his heart is weaken that is only functioning at 20% and that they re also going to be putting in a pacemaker. That if he got his act together and lost weight and stop smoking that he may have about five years. I am devastated and reeling from all this information and just needed to have some confirmation that what he said is true. How can you function if your heart is only working at 20%?
