The challenges of life.

I was recently diagnosed with diabetes. Part shock, part I knew it was coming. You just never want to hear the doctor confirm that it's true. I had gestational diabetes while I was pregnant, so I knew what was expected of me. But that lasted only 3 months, this is a lifetime.
I attacked my "disease" with vigor. Changed my diet, exercise everyday. Sometimes it was tough to get on that bike, but I knew I wanted to be there for my family in the long term.
I have caught a cold, and for the first time, I feel genuine fatigue. My muscles hurt. It is tiring to chew food, my jaw feels like it's been chewing through rocks. The muscles in my arms feel like I've been carrying rocks. It is very trying to get through the 20 minutes of cycling (2x a day) right now because my leg muscles feel like they are ready to come out of my body. But a can't take a break and here is why: when you are sick, your body wreaks havoc on your sugar numbers. So your numbers tend to be higher. Exercise helps to bring them down. So, I'm in a sort of quandary. Do I wait until I'm better to exercise again, or do I suffer through it? I want to stay healthy, but is it at another expense?
