first trimester blues

I'm 6+2 today and I....am...literally dying. Not literally but if this is what death feels like.....then my my my my. 
I have no energy, no appetite, an awful awful cold. It's so hard to brush my teeth in the morning because I gag the whole time, I gagged so hard this morning I thought I gagged up my esophagus. 
I'm a gymnastics coach and it's so hard so so so hard coming to work everyday and being energetic. 
What can I do to help make it through each day?????? Thank you!!!!!!!
