I assumed you were going to say something far more complex than diabetes!
It's diabetes, the most you'll have to deal with is the odd hypo
Posts like this are totally ignorant of the reality of what it means to live with type 1 diabetes.
It is EXTREMELY complex. It is incredibly dismissive to pretend that it is not. It is wearing and relentless and diabetes burnout is very common.
I have lived with it for 25 years and have met many, many people with T1D, all with various experiences ranging from the lucky people who have the magic combo of good resources and not being brittle right up to friends who are not so lucky, who have lost most of their vision and are on dialysis and have had heart attacks in their 30s.
NONE of them would say oh diabetes isn't complex, just the odd hypo 
They would all agree that it is in fact hard work, requires constant attention, and that there is a significant mental and emotional toll attached to the constant awareness of what your glucose is doing, at any time.
Exercise can make your blood sugar go up, as well as down. Pain, weather being particularly cold or hot, running for the bus, a bad night's sleep, a tense exchange with a colleague, the adrenalin from doing something like performing on stage...the list is endless.
A fucking shower or brushing my teeth is enough to make my liver do a glucose dump OR send me freefalling into a hypo depending on how many other variables from the above list have happened that day.
But it's not complex. Right.
It honestly makes me despair at times how NOBODY understands this disease, unless you have it or a close family member or friend have it.
I speak from a position of immense privilege with the most advanced technology available in the world - an insulin pump which receives feedback from a glucose sensor on my arm, and every 5 minutes changes the tiny pulse of insulin that is administered into my body.
More importantly, I have an incredibly supportive wife. I am lucky - when I go to sleep, I feel safe that I have my sensor to alarm and scream like a banshee if I go dangerously low, and if I cannot wake up my wife will call the ambulance.
Because I am fortunate enough to have these resources, I am so well managed you wouldn't know I have T1D to look at my bloodwork - unless I'm premenstrual, then all bets are off 
Despite the tech, my "perfect" a1c of 5.2 (with a standard deviation of just over 1, so not an artificially good a1c made up of highs and lows...) requires a lot of hard fucking work. Maintaining those numbers is a neverending slog, especially around ovulation and period where I have constant broken nights spending hours coaxing my numbers to where they should be.
T1D is work.
