I must admit some people will consider me a bit of a risk taker with some of my hobbies but I always consider myself to be a risk minimiser.
Take climbing. I frequently go rock climbing which many people think is dangerous. Sure, you are more likely to fall if you climb than if you spend your time playing computer games. But you are less likely to fall if you check your equipment, trust your climbing partner, only go out when the weather forecast is favourable and climb routes within your capability.
I think of diabetes in a similar way. You may be more likely to lose a leg if you have diabetes than if you don't but you are much less likely to lose a leg if you manage your diabetes and don't let your blood sugars get "very bad" for long periods of time.
There are different ways of achieving this: some eat the same thing every day, do the same exercise and take their insulin at the same time every day. Others give themselves more flexibility but test their BG regularly, carb count, correct, learn as much as they can and have a bit of fun along the way.
No one can 100% reassure you that you will not have diabetes complications but you are in control and decide how much "risk" you want to take ... as long as you remember to measure your BG regularly, are honest with your diabetes team and learn as much as you can.
Diabetes can be overwhelming and when it feels too much for me, I look to amazing people with type 1 and think if you can act (Halle Berry), play rugby professionally (Henry Slade), perform in an internationally known band (Este Haim) or run a country (Theresa May), I can get through my day without avoiding the world completely.
