Anni, hon, I hear you. What you are going through is the pits. 
I hope your endork is cooperative – and even if he does suggest sulfonylureas, it doesn’t mean you have to accept them. I was offered Metformin when it first came out, but insulin was working just fine, and I couldn’t see any reason to accept the side-effects of Metformin, so I refused it.
The interesting quandary on sulfs is, if you’re like me, they will do absolutely nothing – working no better and no worse than sugar pills (well, maybe a little better – sugar pills raise the BG!). On the other hand, if they DO have an effect, then it means you do have a significant beta cell mass, and the cells are susceptible to being “goosed”. That’s when the hypoglycemia hits. Personally, I’m glad I didn’t respond to sulfs – they are really questionable. But just remember that with insulin, hypos hit too.
Talk in detail with bsc – he can tell you exactly what he did. I hope your doctor will authorize Levemir, but in bsc’s case, his doctor would authorize NOTHING, so he did it with NPH and R, which is what we all did, lo these many years ago. While it’s true that these insulins are not as CONVENIENT as the newer ones, they still work – you just have to work around their idiosyncrasies.
Of course, it goes without saying that if you decide to start on your own, you have to be ULTRA-cautious. And willing to treat your body like an intricate science experiment, with all the documentation, and careful varying of variables, and all that stuff. Which I’m sure you’re willing to do! 
Hoping for the best for your daughter – the uncertainly is mind-killing. Hugs!!
