Reduced movement?

I’ve been going through something very stressful this week (a potential divorce) and the stress has been making me sick. I’ve been having stomach issues from all of the anxiety and can’t really eat anything without throwing up or having it go right through me. Today, I haven’t really felt any movement other than this very subtle sort of seizing? My abdomen sort of feels like it’s shaking/jumping. This doesn’t feel normal to me at all and I’m super concerned. I called the midwife on call but haven’t heard back yet and I’m not sure if I should be super concerned or not. I’m 26 weeks tomorrow
