Dollar Tree employees are nice

So this week I have been feeling like I am about to pass out quite a few times. The first time wasn't too bad & I figured it was from low blood sugar or something since I was waiting for my food at Panera. So I made an extra point of trying to eat something every 2 hours or so and I keep a whole snack jar in my purse. The last two times though, I had eaten fairly recently. Today was by far the worst & most embarrassing. I was in the check-0ut line at the dollar tree and I really felt like I was about to pass out - I got really hot, blurry vision, felt sick, everything - so I decided my best option was to lay down so I didnt whack my head if I did faint. Apparently, I must've gone really pale as well since the manager rushed over to me and helped me down, they got me a chair & some water and after I stripped some layers off and sat there for 5-10 minutes, I started feeling somewhat better. I was soo embarrassed but everyone was so nice. I had just eaten a bowl of cereal before I left the house, so it couldnt have been low blood sugar. My only guess now is a maybe a drop in blood pressure, I usually have low blood pressure to begin with. Im not sure though. I guess it if it keeps happening, I'll give my midwife a call and see what she thinks. Apparently, I am not to stand in lines for a while.
