I’m a worrywart too! But I’m trying not to be too paranoid now that I know how to manage my condition well. I’ve been known to test 3 times within the same hour or test for no good reason and then see that my reading is okay. It’s fine to be worried but as someone once told me, you wanna see life through diabetes not diabetes through life.
About your high morning numbers, you may have dawn phenomenon. I’ve never experienced it but there should be a thread on it somewhere in the forum archives.
