Just got a job but. . .

So I applied and got a job on the spot yesterday, I didn't sleep for 25 hours that day. Well I work for a fruit company for cherry season and it was really cold and I only had a light jacket. I was dying to go to bed and it felt like every hour took a lifetime to go through!! But now I can't tell if I'm getting morning sickness or if I have a cold and the flu. I'm really dizzy when I get up, it takes a lot to keep my eyes open and I can't stop sneezing. I feel really nauseous and I've puked one time today. What's wrong with me?????
