Hbp With Anxiety!

Hi,
I am suffering from hbp since 15 months before and in medication until now .Right now my bp is still gets higher and lower it goes up and down not remaining constantly like sometimes it is 120/80 sometimes it is 150/105
is it ok?I asked my dr about that he told me that it is due to my anxiety feelings .Yes I feel very much afraid that I might caught up by negative effect that hbp have.I want to ask all of who suffers and are suffering from high bp that even after taking proper medication indicated by the doctor does your bp remains normal always???????? :? I don't think so .
My heart rate is near 45-50/min at rest .Dr. Says it is due to medication that I am taking and is ok?It is ok?I always feel lightheadacheness and dizziness when I start to walk ?I have done every test and report is normal says Dr.Dizziness was appeared after taking medication as long as I know .I am 26 .
