Hallo again
@A.n.g.i.e , hopefully you'll get a few more views in this forum.
I just wanted to ask, do you have a diagnosis as to which type of diabetes you have yet? (Probably T1/T2 though there are other kinds).
If you are T1 then you are stuck with insulin, I'm afraid, and though there's a steep learning curve it's not the end of the world. If you are T2 then there are more options, in particular reducing the carbs in your diet may allow you to reduce or eventually come off the insulin.
Basically, T1s don't produce enough insulin (eventually none at all) so they need to inject to replace the insulin their body should be producing. T2s have a problem with using the insulin that their bodies produce (typically over produce at least at initial diagnosis) they are insulin resistant. So the issue for T2s is that their bodies don't tolerate carbs well, the issue for T1s is that they need to match their insulin to the carbs they eat.
It sounds like you have been put on a basal/bolus regime : basal is a 24 hour insulin that carries you through when you aren't eating (eg at night) and the short acting bolus acts to process the carbs in your meals (and sometimes as a correction dose to lower your blood sugar if it's too high).
Now your team will help you work out how much insulin you need : some people need 10 units a day, others need 100s, so there's no one size fits all there.
You don't need to get the hang of this all in one go: diabetes is a marathon not a sprint, hopefully your diabetic team will be keeping in very close contact with you.
Stopping the wall of text for now, lots of virtual hugs, will be able to give more targeted advice if you can tell us which type of diabetes you have (though your team may not know yet).
Lots of virtual hugs, feel free to have a browse the forum and join in and ask questions wherever you like.
