If you're not eating regularly, your blood sugar could be running low and as a result you feel horrible.

I agree that you should see a doctor asap.

It could be diabetes/ high blood sugar, or it could be hypoglycemia (low blood sugar) and/or pre-diabetes. Or it could be something else entirely- I don't know.

If I were you, I would try to have something to eat at least every four hours (even if just a snack) and also try to have protein with every meal. It would also be good to watch out for highly sugary things as those might mess with you.
