Severe Morning Sickness!

I just can't stop throwing up. I can't eat anything or keep anything down. I feel very dizzy. Just so tired of throwing up. My stomach is so empty that it hurts. I have nothing more to vomit but I still feel the urge to. What can I do to stop this? I can't go to work like this. Can't do anything. Just want to stay home in bed all day with a bucket on my bedside. Will it ever go away? Because I really don't think I can do this.
