Depressed

I'm pretty sad these days. I wake up everyday nauseous and tired and it lasts all day long. I don't know what to do anymore and I can't take feeling like this everyday. I can't function at work...I can't function at home... My BF is becoming impatient with me... My daughter misses playing with me. I'm just sad about all of this. All I can do is hope that this ends in the second trimester and I'm not one of those people who have to deal with this the entire pregnancy.
