Calling all NURSEs

I went to the dr today and went in for a sore throat she told me I had really high blood pressure and my heart was beating fast. All she told me to do is drink a lot more water. Anything else I can do?

Now that I’m going to sleep I’m thinking the worst and don’t even want to go to sleep cause I feel like my heart is beating very fast.

(I haven’t had a cup of coffee since last Wednesday so almost a week, only been drinking hot teas for my throat and water)
