Like "What you posted sounds exactly like the feelings I have on many days or rather used to have. I still test like I am supposed to. What I do now is when my reading is too high, I write down what I ate and keep track of it to see if I do it again do I get them same results. This helps me. Also, I rely more now on my A1c test. I strive to keep that within a good range and worry less about the sometimes high scores I get when I have messed up my carbs for one reason or another during a day. We are all different. And we ALL get discouraged. YOU ARE NOT ALONE IN THIS. How was your last A1c?"
