Morning sickness or 24 hour bug??

Yesterday morning I woke up throwing up like crazy it was a all day event, and I also had diarrhea, I couldn’t keep any food or drink down the whole day it always came right back up I was super dizzy and light headed. I could hardly function. Now this morning I’ve been able to eat and drink a little and have yet to throw up but still feel really light headed. Any ideas on what I should do?
