As far as I know depression is only a mental health problem when it's not being legitimately caused by anything. Personally I am totally ****** off but I don't think there's any great secret why. I don't want to be prescribed some sort of pills that will make me dance around happily loving the fact that I can't really do anything other than sit around nursing myself.
As to having kids I wouldn't even think about it, by the numbers given here it is a three times greater likelihood that the baby would develop diabetes, and I have read that it is a 1 in 17 chance if the mother has it. I would not sentence my worst enemy to this let alone my child. I was never someone who definitely wanted children but it would have been nice to have the choice, I do not feel that I can reasonably make that choice anymore.
I have read about 12 to 20 years reduction in life expectancy, I would normally expect to make mid 70s perhaps so perhaps around 60 is a realistic expectation. I did not know that I was already nearly half way through my life at 24 but apparently I had better get used to that idea. I am also not very anxious to hang around until I'm 90 on the basis that I know what is very probably going to happen to me and it is not very nice, I see it every time I sit waiting at the clinic and it is literally a nightmare.
In the end I have said the same thing, it sucks the fun out of everything, it reminds you it's there just often enough that you can never really get away from it. It's almost exactly designed to be utterly utterly hideous and miserable and if someone told me that oh, it's been a big mistake, it's not diabetes and you actually have six months to live, my first thought would be thank god for that.
