Oh, that sounds like how I felt when diagnosed...! Good news then: You're not about to keel over any time soon, and there's LOADS you can do yourself to get your blood sugars back into the normal range. Even without medication! You're not on a runaway train here, you've got the brakes available if you want them, as you just have to make a few changes in diet. Simple, no?
@xfieldok already referred you to The Nutritional Thingy, and I'm hoping that'll put your mind at ease some. You're going to be okay. I wish someone'd told me that when I thought I had one foot in the grave (with the unrelenting fatigue I would've halfway welcomed that rest!), but yeah. You'll be fine. And you'll get your energy back too. I promise.
