Low blood sugar attack!

So, Wednesday I became very sleepy at work. I thought that is all it was being tired, but I could not even concentrate, a coworker realized she needed to eat at 3 since she had not eaten all day!! That made me think I might need a snack. Unfortunately all I had was summer squash and a tangelo, I heated up my squash and started eating and instantly realized this was my problem. I started to feel the hunger instead of the fatigue and it did help, but I needed more. I was nervous because I usually save something to snack on in the last hour of the work day. I was drinking water an slowly eating my fruit. I chewed on gum and texted my husband I was starving and needed dinner fast. Since we were both tired and hungry and unprepared we ate out. I felt better, but my body was still recovering which does not feel good. I am still not feeling the best even today. I feel like binging on yummy foods would make me feel better, but I know better. That might help me short term but long term I gain weight. I don't know what triggered this on wed I have been doing great. I could not have coffee today because my blood sugar is not under control yet. I am eating, but i still have the need to eat, plus I have a headache and other crappy feelings that are symptoms. If I had the food here I would totally make myself a plate of nachos and cheese and something else to try and set things right in my body... I do not have those things, but I ate pb2 and yogurt and a healthy lunch of a tortilla pizza and grapes and a couple of snacks, plus I have been napping and that is not even helping...:(
