good days bad days

Im not feeling any better. I so tired of my blood sugar dropping im do tired of having headaches im so tired of not having any energy. Right now it is not a good day. I am constipated due to the low carb diet I tried to drink a little juice to help with that and my sugar dropped to 77 and now I have a horrible headache.  im off balance like im on a boat rocking. I am so tired I just want to go to bed. I question if maybe the doctor should have did some sort of test to make sure I have this new diagnosis my confidence is waning. maybe if I could find someone else who had this but I have not found anyone.
