Morning sickness with toddler and work?!?

So I am coompletely fucked! I thought I had at least 1 more week before feeling this lousy. With my first baby, I got morning sickness closer to 7 weeks, I'm only 5+4 and I'm constantly nauseated, sleepy, hungry and puking if I don't sleep it off or at least lie down. Which means my house is a total mess, my son is being cared for by his dad ( mainly) and my work is being seriously neglected. I'm so worried about getting through the next few months like this. I have work deadlines to meet and I should cook, for my son at least. I'm stessed! Anyone have any advice? I am desperate. How do I survive this phase?!?
