I'm sitting here wracking my brains trying to figure out what to say to you. What you're doing is VERY dangerous, but I'm sure you already know that. I almost killed myself doing something similar last year. You can read about it if you search "My Coma". And I don't think you are being silly at all.
Have you figured out WHY you can't work up the courage to take your insulin? There has to be a reason for it, somewhere in that complicated brain of yours. And my guess would be that it's emotional, because our emotional brains are VERY resistant to all the smarts and logic that everyone in the world throws at us. When I was bingeing on carbs last year, and not taking enough insulin (I never eliminated it altogether), I think my screwball emotional brain was doing a science experiment on how high could I go without suffering any consequences. I knew perfectly well what COULD happen, but I thought I could catch it and remedy it before anything real happened. I'm not claiming this was rational thinking -- in fact, I was totally trapped by my emotional side, and suffering blackouts and hallucinations that I was totally unaware of, and it's only luck that I didn't black out while driving and kill someone else. As it was, I turned my whole house upside down, and my friends, who cleaned it up while I was in the hospital said it looked like a tornado hit it.
I'm not saying your emotional side is telling you the same lies that MINE did, but the fact is that something is leading you down a very self-destructive path. If you can figure out what benefit you are deriving from not taking your insulin, you're halfway there to winning the battle. Mine was, "See, my BG is 576, and I'm still walking and talking!!". Not rational at all, but I'm being honest about it. I don't honestly think I had the desire to hurt myself, but that IS, indeed, what I was doing. It's entirely possible that I was pretending I didn't have diabetes -- denial has been a HUGE issue to me for as long as I've had it, and still is. I'm constantly struggling with denial, even when the facts are right there in front of me (Hi, Mr. Meter -- are you lying to me????)
So, after I got out of the hospital, I made some bargains with myself. One was, that if I HAVE to binge, I HAVE to take ENOUGH insulin to cover it. No namby-pamby 3 units to cover half an angel food cake, and 1/3 of a carton of ice cream. I will also admit that it's a hard bargain to keep, because it's scary to take 10 or 15 units to cover a binge. And more often than I'd like, I DON'T take enough to cover the binge, but I DO keep track and check and correct.
The fact that you're checking tells me that you ARE aware of what you're doing to yourself, and it seems to me that now is the time to figure out what your motivations are, and figure out a bargain with yourself that will solve the insulin problem. Just off the top of my head, which is to say I'm grasping at straws here, one bargain could be that you are not allowed to get out of bed unless you take your insulin. Or you're not allowed to brush your teeth unless you take your insulin. I KNOW how silly that sounds, but when I think of my grungy morning mouth, and how badly I want to brush, I think I WOULD take my shot if that was the only way I could allow myself to brush, LOL!! Of course, you have to think of your own motivators, but I'm pretty sure you CAN think of some. :-)
You might notice that MY motivator is a half-way motivator -- I REALLY shouldn't binge at all, but to me, meeting my crazy emotional brain half way is better than not at all. And meanwhile, I am working VERY hard on finding ways not to let my emotional brain be in control -- finding ways not to be depressed or sad, which is when I'm most vulnerable.
So, I've talked mostly about myself, because I don't begin to know what is going on inside you, but what I would like to do is encourage you to think the hard thoughts and feel the unhappy feelings, and find ways to turn the tide of the battle you're fighting, so that you CAN win the war and be there for your dear daughter, and all the other people who love you!
