As none of your tests are outside normal I'd be wary of talking about hypoglycaemia, but the idea that you haven't been eating sensibly and your body is protesting seems like a decent starting point.
Is reiterate my suggestion you plan and moderate your eating, whilst testing your bloods and keeping a food diary and review that after a short while.
That said, if you are sufficiently concerned you should book an appointment to see your GP and build your data in the meantime.
Good luck with it all.
