Nervousness and high BP. Treatement?.

Dear Doctor, Good Afternoon I have been suffering occasional anxiety issues from the past few years. But it has been agrevated alot in the past few months. I have sometime high heart rate when i am tensed or anxious. But one thing i have noticed more is that, whenever i visit a hospital for a regular checkup, i get nervous and when the nurse check bp using the machine, i am more getting more nervous and always thinks about that my bp will be high and what will i do if my bp rises and all. In the last few months i have visited 3 time in hospital bp reading were 140/80, 150/100, 150/90. But while i reach home i feel relaxed and no anxiousness. As per the blood pressure range, my bp seems to be on a higher range. I have never faced any heart problem like chest pain,discomfortness or nor breathing issue. Am i in need of bp medicines or it is a psychological problem that require psychiatry treatement?. Please help me.
