how do you feel about pregnancy?

At first, I was thrilled. Full of joy and nausea of course. Later I felt that I would provide the best for my baby. Then I was worried that I couldn't take good care of my baby as a working mom. Recently I felt my whole life would change and I was not certain if I can handle all these changes. I have to move away from my husband for a new job. That certainly is not helpful. What is your emotional roller coaster?
