Hi! This Is My First Time Here. So I Will

Hi! This is my first time here. So I will give you as much info about me as I can. I'm a 29yr old mother (yes I'm a smoker, not sure if that helps or makes a difference) no chance on being pregnant (tubal surgery), and I've been throwing up thick yellow stuff (looks like an egg yolk) and I'm also throwing up thick white foamy stuff along with it. I don't have any stomach pain. But earlier it did hurt when I took deep breaths,but I've had that before (pluracy I think... Fluid around my lung) My body is shaky and I feel real weak. It kinda feels like I haven't ate in days, but I have. Right now I'm nibbling on crackers and sipping on ice water hoping it will help. I'm just wondering if this is a virus or something else. Please help, I feel awful. Thank you in advanced.
