Slight hypoglycemia? yesterday i was so tired from lack of sleep that didn't eat much.?

i had no breakfeast, a small lunch and went to sleep early. woke up around midnight and had like 2 handfuls of cheerios and fell back asleep. this morning i woke up and had 2 more handfuls of cheerios and took a hot shower. i came out feeling EXTREMELY shaky. my symptoms matched symptoms for hypoglycemia. I had nightmares all night long as well, i read this was one of the symptoms. I am not diabetic and had a fasting blood test done about 2 months ago and it came out fine. Could I be only slightly hypoglycemic? I am 22 years old, 125 lb. and 5 feet 4 inches if thats any info.
