Udf and the Fire Dept. Long story

Caitlin
Hey ladies, so yesterday I went over to my sisters house to hang out and get ice cream. Shes 34 weeks pregnant and im 15 weeks so we do this alot haha.In the middle of watching a movie we go to get our ice cream, we just walked over to udf because it was just one street over. We get in there and my sister orders her sundae and the guy takes forever making it. Just after I order my brownie sundae and the guy asks what kind of ice cream I want I started feeling light headed. Normally this passes quickly for me, like standing up to fast, see black spots then you're fine. Well all of a sudden I'm on the floor which took me a while to realize because I couldn't see anything. A woman in the store was a nurse and started asking a bunch of questions and they called 911. I was sat in a chair and given water. After 1 sip I spilled it everywhere and everything went black again but I could hear my sister talking to me trying to keep me awake. The whole time all I could think was about my brownie sundae and how it must be getting melted lol. The fire dept showed up and I had a normal blood pressure, but I had a blood sugar of 59 when supposedly it should be at 80. They chastised me for what I had eaten that day but living broke while waiting for my paycheck to come in has been hard, I just started the job so I've been waiting over 3 weeks. But any way, does this sudden low blood sugar indicate anything? I ate right before I left the house to go to my sisters, as well as had a Hawaiian punch(which has sugar) and a popsicle on the way to her house because it was hot out. It's not like I didn't eat anything all day, and I had felt completley fine until I ordered my sundae.
