Overwhelming experience , only 8 weeks

Hey ladies, this is my first post and I'm very excited to be a mother. But honestly, I'm scared as I don't know what. I'm 24, I'll be 25 by the time the baby gets here and even though I graduated from college I haven't honestly accomplished anything. I'm like "yay I can't wait til the baby gets here" and on the other hand I'm like "shucks, what if I suck and go broke trying to raise another person" . So many feelings on top of the fact that the from weeks 4 to 7 I literally was vomiting everyday and was always crying about something. But are these feelings kind of the same for every new mother or am I tripping.?? 8 weeks and 3 days as of today .
