I sure hope there's nothing going on that I'm not aware of. I felt weak as a kitten. I had to take it very easy for that last mile prior to the park. Once I had some food in my belly I was OK again.
For most people (I defer to 10Wheels about the diabetic issue, he knows more about it) a bonk is when one has depleted one's glycogen stores, and simply crashes as you describe. That's more likely to happen in the morning, if one has not eaten, because glycogen will have been run down during the night. But we store upwards of 2000 kcal of glycogen in muscles and liver, and it would seem virtually impossible to consume all that in one night's sleep and 6 miles cycling.
