What should I even say?

I was in a car accident Tuesday on my way to work and I’m currently 8 months pregnant. My doctor checked me the same day and everything was good but she told me to rest for until Thursday I can resume back to work. I went to work yesterday and I was fine but I started to get anxious driving to and especially from work. And now today, Friday, I’m 10 minutes late as of now because I’ve been puking from nerves. I’ve made it halfway down the road to work but just couldn’t handle it. I drove back home and now I’m sitting outside my house debating what to do. I feel so bad calling in again.
