How do you guys do this?

I am at the end of my week 7, and I cannot express how sick I feel. I  constantly nauseous I'm throwing up every morning and often evenings. I work really long days, and I seriously can't keep myself together. Everything I eat makes me sick but if I don't eat I throw up. I have to know how others get through this. I am taking unisom and b6 and some days it helps and some days it doesn't. It's like hit or miss. And I constantly feel awful. All I want to do is lay in bed and slowly eat and hold a trash can. How do other people get through this? Any help is helpful.
