Not feeling any better

We got home and I just got this huge headache or something. My head felt like a brick, I couldn't pick my head up   . Well I then started to see things like floating down from the sky. So my husband called and they said to drink two big glasses of water well, I could only do one or else I'd throw the other one up. Now I'm laying down on my left side. Yesterday we checked my blood pressure and it was good. My pulse was 78. But my feet were a little swollen. But it seems like I have to force myself to eat and anything I drink just makes me want to vomit. Just feel like poo
