That sounds like a really rough patch. Sometimes I have months like that as well. Not quite as spectacular as yours has been, but feeling the burden and stress of one thing after the next can really weight heavy on you.
I went through a spat like that and the way I found to cope was taking day by day. Today may be a mess, surgeries, failed devices (I hate when this happens!), just plain old high blood sugars, it all will come and pass. Life doesnt stop for anything or anyone, but there is a new day starting tomorrow and a new chance at making it a good day. Lets start with that and we can work out the rest as we move along.
Takes Holger's advice and look into Levemir as I have seen multiple folks complain about Lantus. Supposedly, switching will make things much smoother as far as control goes. Having simple things like more stable insulin will allow you to work less hard to achieve the results your after. Its odd how diabetes works sometimes, but if you do a little leg work up front (choosing easy calculated meals and what not) then it makes managing it a whole lot easier. And thats the goal right? Easy management.
Time will pass, MDI will get easier, youll have a new pump, and management will get easier.
