First of all the bipolar disorder
should have no impact on your lifespan, unless you get suicidal.
The only thing that would concern me is being diabetic, since it effects so many parts of your body. Having Heart bypass surgery
only prolongs your lifespan. My grandmother had a triple bypass and lived to just shy of 90.
With the advances in medicine, I'd say your chances of being alive ten years from now are rather good.
That said, healthy or not, live everyday like it's your last.
