I feel your frustration. I think it's totally normal to be just tired of having to deal with it, especially when it takes you away from getting on with your life because you don't feel good!
I feel it's been helpful for me in those times to recognize that as much as we are told that diabetes doesn't stop us from doing anything we want and leading normal lives - especially when we feel that letting diabetes "stop us" or "set us back" in any way also means we have failed at being diabetic, at having the normal BGs we're supposed to be aiming for all the time - the fact is that I *do* have a serious medical condition that sometimes means that even with my best efforts I feel ill or tired where someone without this condition wouldn't. Or that I have to spend time doing things, like treating hypos, or waiting in line at the pharmacy, or filling out forms, that other people wouldn't. Not so I can wallow in self-pity or feel that I'm sick or broken, but just to be honest with myself about the fact that when I feel I have so many extra hurdles and frustrations, it's not because I've done something wrong but because I really DO have extra hurdles and frustrations! And then I realize that all things considered I'm really doing quite a good job coping with it all, and I feel better and more willing to take care of myself
I don't think there's any kind of special solution to this that will resolve it every time, or something you don't already know how to do. The answer is, I think, just the usual hard work and drudgery - treat the hypo, think back on your insulin decisions, look for patterns, decide whether to make changes or wait and see another day. One thing I might recommend is not to have the cheese stick right away, because that will slow down digestion of everything else in your stomach. Wait until your BGs are safely back up, and if you need a "stabilizer" until your next meal, have the cheese stick then!
I would also say maybe don't feel like you need to have permission or confirmation from someone else before changing your insulin doses - if it seems to you after all your experience with your own body and your own diabetes, that the thing to do is change your insulin doses right away, then do it! Or if you think you should wait and see if it repeats, then do that.
