"The hypoglycemia I experience is impending doom, severe panic and the need to eat or I'll die."
Yeah, that's how it is for me too. Sometimes I when I feel it, I need to eat NOW. Or I'll feel like I'm going to pass out and who knows what'll happen.
Several times lately though, I noticed my blood Sugar drops and I don't always get those horrible symptoms. Instead I just start feeling bizarre and my brain starts getting sensations in it, then suddenly I feel like my brain is about to shut off or something, and I need to eat NOW. I wonder if it is "hypoglycemia unawareness" due to running out of anxiety and panic chemicals. Sucking the anxiety well dry.
EDIT: I also get fears almost every time it drops, especially when it drops really low, that it won't raise again. I get this thought running through my head that says "I really hope this isn't the meal where my blood Sugar finally doesn't raise no matter what I do. I hope it's not". All this terror.
