this is probably a stupid question but

Hi ladies. Does this sound like dehydration? 
Headache
Jittery feeling. This ones is hard to explain. Its almost like when your drink too much coffee (i havent had any caffeine) my heart feels like its fluttering fast and im having tge same feeling in my head?
Dizziness, almost like the room is spinning. Or im spinning.
Dry lips (but ive been mouth breathing)
Feeling weak
I threw up and saw black spots floating around
And just an all around ick feeling. 
I know it probably is dehydration. Im having a hard time being interested in fluids and keeping them down. Even sipping small amounts doesnt help me. I just want to see what everyone else thinks before i head to the er for fluids. Im trying so hard to do this on my own. But holy cow i feel like crap.
