Heather, you will not get your blood sugars down by eating spaghetti and toast! That's pure carbohydrate, almost all of which will be converted to glucose very quickly.
In your position, I'd think about eating differently rather than taking more medication in order to eat the foods that are harming you.
There is a danger of permanent damage to your cells at such a high level of blood sugar. Try some srambled eggs and bacon, for example. All of the vitamins your body needs, and no sugar. As Sue said, it's the bread, rice and pasta you need to eliminate, as quickly as you can.
All the best,
