9 weeks, all day sickness and dizziness

Hello, I’m 9 weeks today. I’ve been struggling to keep down food/water for the past couple weeks. I’m constantly dizzy to the point of just feeling out of it and like I might pass out. I didn’t take my prenatals for 2 days and the nausea got slightly better but I’m still extremely dizzy. Has anybody dealt with this and have any advice/tips? I’m afraid to drive sometimes because I’m afraid I’m just going to pass out. Please help me 😭 I’ve tried crackers before getting up, getting up slowly, nothing is seeming to work.
