Morning sickness

Ok so this sounds weird and I don't know if it happens to anyone else, it's why I'm posting. So if I'm nervous, angry/mad/pissed off 90% of the time I end up getting sick. I don't mean to, I don't plan to and I don't want to. But my body knows, even when im trying to calm down or not be so overwhelmed i still get sick. Like 3ish weeks ago I started a new job and I've never done anything like it and got over heated and got sick less then two hours in. Then yesterday I just was so overwhelmed with to much going on I ended up throwing up again. Am I the only one, or is this happening to anyone else??? I'm 22 weeks btw
