i have always assumed that i am hypoglycemic because i have to eat every 2-3 hours in order to not feel really irritable, lightheaded, tired and depressed. lately though i have found that right after i eat lunch , afternoon snack and dinner i have to exercise for 15-20 mins in order to feel normal.

otherwise right after i eat i will feel hot, shaky, and irritable. this seems odd to me since my meals and snacks are very balanced consisting of a veggie a protein and a low glycemic carb. i drink orange juice when i feel like my blood sugar is really low but it is always balanced with another protein.
i am going to talk to my doc either way but i just wanted to see if anyone else had personal experience with this.

it has also been very difficult to concentrate lately. if i go without the exercise i become very tired and irritable, it is diff. to do anything other than sleep.

does this strongly indicate diabetes or hypoglycemia?
i also feel thirsty and have to pee all the time.
