Im super shakey and im really scared?

So earlier i was really dizzy and just laid down (5 minutes ago) but now i am so shaky i can barely even type. I am 11, 5"1 and 105 pounds. i am eating a poptart and fruit snacks with milk if that matters please help i get shakey about twice a month but right now its worse then ever. my mom has hypo glicemia and diabetes if that matters
