Help!

Michelle • Ryland born 11-13-15💙
I am under a lot of stress, lost my job yesterday, and I am almost 17 weeks pregnant. I am so stressed out and depressed that I haven't been able to eat anything yesterday or today or drink anything. The thought of food makes me violently nauseous. 
What do I do? I am sure I am already dehydrated. I am worried about baby. I've been having cramps since yesterday with no bleeding, not sure if it's round ligament pain or putting stress on baby. 
Please respond!
