Weirdest pregnancy

First time being pregnant, I found out extremely early..I am almost 5 weeks pregnant but I have the worst morning sickness of my life and it is all day and night. Throw up whenever I eat something. Can barely keep down water. Someone please help me! I have my first appointment around 9 weeks but by then I feel like I'll die. Definitely did not expect to feel this miserable while pregnant. I didn't even think it was possible to find out I'm pregnant this soon but my tests are as clear as day and I definitely didn't think mornin sickness was possible this soon.
