What Do These HbA1C Levels Indicate?

Question : Hello. I have been diagnosed as Hypoglycemic through a couple of A1C blood tests. My first was 4.5 and my second was 4.9 after the Holidays and binge eating. In January of this year, I had a major episode ( vomiting, personality change, moodiness ,etc ) that sent me to the Doctor. I was sent to a Dietician in March and have been put on a low carb diet ( 120 carbs per day ). It brought my A1C up to 5.2 . Recently, I went through an episode where my blood sugar dropped from 143 to 103 in less than an hour ( I had eaten maybe an hour to an hour and a half before the episode ) . My symptoms were : my eyes didn't want to stay open and felt like they were bulging from my head. I had a headache , felt strange, and my family said my eyes looked funny. Now, I'm getting hot flashes and waking up feeling like I'm covered in a light sweat. It's been going on for a few weeks now. I get upper abdominal pain ( above the belly button ) occasionally both before and after I eat and then feel sick after a meal. I've had bouts of restlessness and have issues sleeping sometimes. I struggle t wake up a lot of mornings. I had a hard time walking in a straight line one morning after waking up. I am 45 so, I'm aware some of this may be pre menopausal.... but what else is going on ? And what can I do ?!
