Lately I've been really tired shaky dizzy irritable and had bad migraines not diabetic blood sugar 60-70 what's going on?

Feeling bad. Given your symptoms, an in person exam by a doctor is needed. You may have sinusitis or inner ear inflammation-- otitis media or labrynthitis. Consider bloodwork such as a CBC, basic metabolic panel and thyroid test, as well as having a neurological exam, and perhaps a head CT scan and ECG. Please go to an urgent care today.
