morning sickness advice

I'm 11 almost 12 weeks and I've had really bad morning sickness well just the feeling like I'm going to throw up I could eat or drink anything ....that went away for a bit until I woke up this morning and I can't stop ganging and dry heaving I figured maybe I need to force myself to eat a little something cause it gets worse when I'm hungry that was a big mistake I've ran to the bathroom thinking I'm about to throw up but nothing it's so bad idk what to do
