Super dizzy and nauseaus.. nervous

Is this even normal, I am 37+4 and incredibly dizzy and nauseous I feel awful. I’m so exhausted and running after my 18-month-old is not helping. I don’t know why I feel so awful all of a sudden.😬😬😬 I have a schedule csection for the 17th but we’re all hoping my water breaks so I have a chance to attempt vbac. But doesn’t look like it’s gonna happen. Any tips? Anyone feel this awful at the end? I’m honestly terrified.
