Can't keep anything down

Julianna.
I need advice ladies....
These last couple of days I 
-can't keep anything down
-comes out of both ends
-bd left to Afghanistan 
I feel like im on an emotional roller coaster and I'm worried if I'm dehydrated. Should I go to the er? Should I try to force down water in hopes it doesn't come back out ? Should I rest? 
I'm a first time mommy at 9weeks and I feel all alone. 😔
