Help Me With This!

My friend has diabetes and I would like to know about it... My feet fell asleep 4 weeks ago and hasn't happened yet again but my friend says I might have diabetes. I am never hungry, never thirsty, not over wieght, not loosing weight (i am just fine) I have 19/20 vision and its not blury, my feet and hands barley fall asleep and I am not tired or drowsy. My friend wants me to make sure are there any more symtoms... And the cure for diabetes... How is it coming along and when is the best guess they will find it? Another question- is diabetes a bad thing to have (i mean socialy)
thank you
