Stomach bug….. *gross warning*

Three days after seeing a post on here about a stomach bug going around, I finally got it. My daughter got it two days ago and it was bad. Throwing up while she was having diarrhea at the same time on the toilet, multiple times that day. She handled it like a champ though, no crying, nothing. She’s only 3.5yo so I was very surprised she didn’t freak out. The next day she seemed completely fine. Last night my husband and I had sex because it had been a couple days and an hour later my stomach was hurting like crazy and my head was killing me. We decided to go to sleep and then I woke up at 5:30am throwing up and shitting the bed. I feel horrible. I feel disgusting. I feel so so dehydrated. He’s out buying Gatorade and white bread and gingerale. I’m scared he’s going to have it tonight or tomorrow morning. Of course right before Halloween. Our daughter is going to be so disappointed. I’m dreading her waking up today (it’s 8:54am while I write this so she’ll be awake any minute) and I still am on the toilet with diarrhea dripping out of me and snot/throw up running down my nose. Please send help.
