I haven't been diagnosed by a doctor, however a nurse I know (she's been a nurse for 25+ years, and has hypoglycemia herself) has told me that my symptoms match hypoglycemia exactly. Plus, the "treatments" have worked; if my blood sugar is low (or I have those same symptoms), I eat something with protein (I could be mixing up words here), like crackers or a muffin or a granola bar, so I don't have the sugar crash. I do agree that I would benefit from talking to the doctor, I'm trying to pressure my dad into making an appointment (cause whether he believes me or not, the symptoms are there, and are a problem!).
