Being Hypoglycemic?

I think I became hypoglycemic, I have symptoms. I am 22 years old female, student still. I am always sleepy, I can't concentrate on class, and I know that is not depression. I didn't lose the weight and I don't have eating issues. So, what are the sure signs of Being Hypoglycemic? Does anyone know?

Hi there, I guess you could be. I am hypoglycemic. I have symptoms such as slow response time, grogginess, the inability to focus and lots of sleeping. First I thought that I am depressed, but I am not I am well built and healthy looking, so it is not because I wasn't eating and lack of food lowered my glucose level. I am not sure still how it started.

I'm having symptoms too... except I seem to be experiencing mood swings, i feel groggy & tired, i get cold sweats and sometimes even almost pass out (especially in the mornings). I also get blurred vision and feel sick... The only way I feel better is if I drink juice or eat something..

What have you done? Is there a way to diagnose it? I'm scared as anything over it.
