Nervous about blood pressure

I’m nervous about my blood pressure usually when I go in for my appointments it’s at 137/93

Which I know is high already. Well today I went in and it came out at 150/98 and I was surprised it’s never been that high! So they had me go into the room and lay on my left side and a girl came in and took it manually and it was in the 130s. Is there anything I can do to make it lower didn’t eat before my appointment and it was already 1:30 could that have anything to do with it?
