Diabetes is really a global disease that has infected and suffered humankind for so many years now, this disease oh my God has maltreated human being like an animal without any consideration. I feel sorry to know that you're one of diabetes patients, it hurt to know that your father was diagnosed by diabetes and that lead to his dead. How I wish we have the power to eradicate disease and throw it away from earth, life would be much better to live. Stay safe.
