So sick I can't function!

Tiffany • 26. 2 girls already and just tested positive for another baby! Yay.
Anyone else with me? I can't stand the taste or smell of any food or beverage. I'm severely dehydrated and shaky and weak. I got some medication I was reluctant to take but I can't go on this way any more! I have 2 kids I feel like I am neglecting as well as 24 kindergarten students I teach. I cry every day because while I am excited I am also miserable and feel helpless :(. I need some support!
