Whilst not easy or a complete answer switching off from the news other than in limited measured doses helps anxiety. Doing what you can to preserve you health focuses anxiety in a positive direction and makes you feel more in control. This applies particularly to bgl control. You cannot directly control every aspect of this but you can some.
Eating too many carbohydrates will increase blood sugar and need for insulin in type 2 both of which make the underlying problem worse. Switching to a lower carb (not just sugar) will help enormously to lower bgl. As you are on insulin you need to monitor closely to make sure you don’t make changes too quickly and go too low or get a supportive dr to change medications to avoid the risk of hypo. Most type 2 going low carb will need their medication reducing or even stopping as they were set up for higher carb eating and needs changing alongside eating habits to stay matched safely.
