I don't have diabetes and for the last days my blood sugar is above 180s all day long. along with it i have severe anemia and no energy even to walk, when i walk sugars raise then drop dangerously fast. what's happening?

This is significant hyperglycemia&I consider you diabetic as the elevated blood sugars are persisting. Have you been evaluated by a physician for your anemia & hyperglycemia? The gold standard for diagnosing diabetes is an oral glucose tolerance test. Have you eliminated sweets& cut down on starches yet? Make sure you get accurate diagnoses of your anemia&hyperglycemia& get appropriate treatment
