HI LIZ!!! The bottom line for me (and probably others as well) is that there is an ebb and flo to everythihng in life. In Feb. I will celebrate my fiftieth birthday, and thirty eight years insulin dependant and I have no eye damage (whew). I am doing very well because I worked very hard, was very lucky and had great support. Not only is what you are experiencing perfectly natural, it would be funny if you didn't feel somewhat tired.
When we are diagnosed, we are usually physically ill, but we don't know why. Shortly after because we are able to manage our blood sugar AGAIN (ha ha), we feel better physically but are stressed mentally because now we have a much better idea as to what we are in for. And yes, yeccch. Policing our emotions is as important as watching our sugars because they can be both dependant and interdependant on each other.
This is a fancy way of saying HOLY #$$%%^^ there is a LOT to deal with here. Like all of us I am certainly not an expert and I learn more everyday, and you will to. I am proud of you for voicing your concerns here because NO ONE SHOULD EVER SUFFER IN SILENCE and our emotions when skewed by diabetes are turned into a valuable tool to create more damage within, and without. Even the Devil enjoys help from those who volunteer. It makes "the job" easier (ha ha) and this of course is not an option.
The very second you are quiet about it , it knows it has you and we know that will never happen. MY advice? Be as silent and sneaky and severe to it, as it is to you. Without driving yourself or others crazy run the best reasonable blood sugars you can and when you think the timings right TALK YOU HEAD OFF!!!
