A huge life change

I became a type 1 diabetes back in 1998. My mother was a type one diabetic and died from diabetes related issues. How her first three children all have type one diabetes. I am a twin as well and yes my twin is also a type One diabetic. I had to change my life due to this disease. My doctor stated it was a bit strange that three out of 12 children by one women can have diabetes. I exercise and the glucose readings go sky high when the doctor states it should go down. Yes, I have this fear. I no longer exercise as strongly running four miles a day and sit ups times 100 per day. Have had a heart attack and health care is affraid of paying for pump so a shot 4 to five times per day. No sex life and depression meds are not my way to go. eat only 1200 calories per day. Medical payments are a bit high, so I only get what is really needed i.e. insulin instead of blood pressure meds. Thanking about transplants.
