Hi Ladybird,
I will try and help you understand individual.
If you came to my house for lunch and I dished up a meal that I know would not raise my blood sugars then you may think, "OH great, if I eat the same as Catherine then my blood sugars will be fine". That is not true because we are different people and we cannot assume that because someone else can eat something and it is alright for them then it will be alright for us to. Your blood sugar rise may be higher than mine.
You may go and lunch with someone else, they dish up a meal suitable for them and you end up with blood sugars that are too low.
Does that make sense?
If somebody is using insulin then they adjust the amount of insulin by counting the carbs in the meal and injecting accordingly. (I am sure that some ~Type 1's may not agree, I am doing the best that I can guys
). They don't always get it right and the same meal may have been OK when they ate it the previous week. Complicated it is and we are all different.
You will find that just when you think you have grasped it then something is changing and your blood sugar is either too high or too low for no apparent reason. That is the nature of diabetes, it tries to beat you all the time. It may be that your fluid intake is too low, you have been very energetic or have had a more sedentary day, you may have a cold coming, you have experienced more stress. There will come a day in the very near future when you will know you have cracked it but take it at a pace that suits you. Nobody is judging you but I think you are being too hard on yourself.
Hope that helps,
Ask away at anything you don't understand and if it is still not clear then ask a question about what is bothering you from the explanation you have been given.
Compare it to having driving lessons. The first lesson is a complete mystery to you, well it was to me, and then it gets easier and easier. After you pass the test it is then that you realise that you are on your own, nobody to guide you. and I personally think that is the most scary time. The difference with trying to mange the diabetes is that you are here and there is always someone to help you.
