Nausea 😷

Adriana
Hello everyone! 
I was taking a nap when out of no where I got up and felt very nausea. My heart was racing, I got kinda dizzy, my body was shaking and I started to get anxiety. This has happened before but not like this. I felt fine throughout the day and now that I have woken up I feel like I don't want to eat anything. I hate throwing up so I'll do anything not to. I just want to know what happened. (I am not pregnant or trying to get pregnan I am also not sick.) has this happened to anyone else before? 😕
