Hi
@kmtech
This is my personal opinion: I have both conditions.
My epilepsy was a great concern, right up until I became diabetic, but now I hardly think about it.
I did worry about seizures and even death (there's a rare condition called SUDEP Sudden Unexpected Death in Epilepsy which can strike randomly), but other than taking my medication it had little effect on my life. It bothered me more when I was young, but as time went on and drugs improved, it became less of a problem. It does affect others dramatically, if they're at risk of frequent seizures. I suspect the main cause of death is from injury - I've had seizures and hurt myself in the fall: it would be possible to fall into the road or something.
Now I'm measuring my BG, taking (great) care what I eat, counting carbs, injecting insulin, exercising regularly, etc and I have the risks from hypos/hypers if things go wrong. The dangers from diabetes are well documented (both short term from hypos and DKA, and all the long term damage from high BG levels). I.e.
@Enclave is right: it's possible to control Diabetes.
Unfortunately, you don't get to choose which illness you want (and some people end up with multiple conditions) :-(
