Worst Nausea EVER! Cant eat or drink!

This is my first pregnancy and I am having the worst time with nausea. Ive only puked once, but I can barely get out of bed without feeling like the world is spinning. I have tried all the tricks (ginger candies, B6, my doctor even recommended unasom...) NOTHING is helping and its at the point where I can barely eat or drink. HELP! Please tell me I’m not being a baby!
