I love to eat ice cream but I have diabetes
I am sorry to hear that you have diabetes. Are you afraid that eating ice cream will increase your blood sugar level?
Yes, but I do it so often. I need to control myself.
It's wise  to monitor your sugar consumption. I understand your temptation of eating ice-cream but you should cut it down to remain in a good health.
I try my best to resist the temptation but it's tough. In the end I say fuck it and eat ice cream.
If you have a disease you need to control you diet as required. Maybe you can consider a brand with less sugar or making your own recipe.
