Sick day

So I had to stay home from work today because of the extreme nausea and fatigue (I work outside with animals and it’s 3 degrees and I just couldn’t do it today.) But everyone is saying “you look fine,” or “you look like you’re feeling better,” or the worst “what’s wrong with you?” I haven’t told anyone I’m pregnant yet and don’t want to anytime super soon, so I feel like everyone thinks I’m lying to get out of work 😩 I have major social anxiety so I’m having a really rough time.
