Early Pregnancy and hating it....

Warning in advance, this is a very negative post. I'm 8 weeks pregnant. See the heartbeat and everything looked good. I was so happy to learn we were finally pregnant after years of trying. But now that's its been a few weeks... I'm just overwhelmed and freaked out. I'm 30 years old and this is my first child. And I'm sick all day for weeks now, I'm to tired to do anything it seems like. I'm depressed. Everyone in my life is overwhelming me with their excitment. And I just feel anxious. Anxious about delivery, and being so big and trying to eat healthy and not gain to much weight and then having a newborn. I just feel so so overwhelmed and I don't know how to handle it. I don't know if it's the hormones or just reality Setting in. But I'm freaked out and I wish I could feel better and more positive. Anyone else every experience this?
