I know what you mean about being afraid of being sick.
I wasn't actually sick when pregnant but I spent the whole 9 months on the verge of being sick. Yes, no, yes, no, yes, no. It was like standing on the edge of a cliff for 9 months. I kind of wish I had thrown up, then it would be out and done with once a day.
The trouble with pregnancy is, it's never the same for each woman and you can't predict how you'll feel.
However, compared to pregnancy, giving birth was a doddle. Painful but it was only a few hours compared to a horrible 9 months, and we went home the next day. And you get that Goddess feeling when you give birth, which is fantastic.
My best advice is find a group of supportive, loving and loyal friends and family to support you when you're pregnant and have a new baby. That's what I wish I'd had, but I didn't plan anything and so was just left to struggle alone for 9 months with no one even visiting.
