Nauseous & Anxious

I just want the first trimester to be over. I'm miserable, this go around. I'm trying incredibly hard to be excited, but I'm just not, even though we tried for over a year and finally conceived. I guess I have a lot fears. Like my daughter (2 next month) won't get the one on one attention anymore. The new baby won't have the strong bond me and my daughter have. And I think being sick 24/7 is just making it worse. I don't think its hit me quite yet. Anyone else feel this was, or have I completely lost it?
