welcome aboard! You are in a serious situation and it shouldn't be taken lightly. Diabetes can AND will get the best of you... if you let it. If you don't control it, it will control you and as you've seen it can pick you apart limb by limb. You only live once and you should take better care of yourself! It's not too late to get a handle on this and turn it around.
I have a friend that's a insulin dependent diabetic. He'd make me a nervous wreck, I've seen is BS drop so damn low time and time again. I'd offer him juice, food, what ever and he'd always refuse. It got to the point that I'd have to force it on him, just to get him out of "La-La land".
You need to finish the journey that you are always "starting".
I've been trying to tame my bluntness lately but you asked for an ask kicking.
