Week 9 and feeling terrible

I am currently on week 9 and I am feeling the worst ever. I'm nauseous, hungry, so extremely tired and moody. I am super cold and have the chills. I feel like I have the flu. My body aches and I have little zit bumps on my face. I also have hot flashes and feel like I am going to pass out. I can barely make it through a day of work. It feels like it started at week 8 and got worse. Anyone else feeling like this?
