That’s it, Halloween is cancelled

Hello, 5 months pregnant here. I went trick or treating with my baby sister and my mom while my husband followed in his car. I sent my husband back to the house to grab an apple and peanut butter since I have GD and didn’t want my glucose to go wild. We started walking around the neighborhood until I got tired and we followed my sister and mom around in the car. The neighborhood is PACKED with parked cars, running kids and cars with no driving etiquette. It’s very anxiety inducing for me (I’ve never like being in cars) but we went to a couple of houses before calling it a night since I have to pee. We drive back to my parents house to drop off my sister and mom and as soon as I get in the house, I choked on my spit and it triggered me to start puking on the floor..my dad was in the bathroom so I wasn’t able to run in there…and I also peed myself due to the puking. Glad I did it at home instead of in front of the neighborhood kids. I’m still embarrassed and feel horrible right now driving back home while feeling nauseous and wet. I just want to cry in the shower.
