Bad morning sickness, thoughts?

Im currently 6w 2d and have the worst morning (all day) sickness. The only things I can eat & drink without having problems are Hawaiian bread and sprite. I can't even drink water. I decided this morning that I'm fucking thirsty since I've barley drank any water in a week, took 2 drinks of water and I had to run to the bathroom and i just threw up a bunch of liquid. I want to go to the hospital but I'm afraid they'll just tell me to rest and try ice chips (which I've tried). I have no energy from not drinking enough water or eating and I'm honestly worried. This is baby #2 and it wasn't this bad the first time with my daughter. Idk what to do.
