Re: Advice on how to lower BP?
Do you drink? My doctor had me cut out alcohol all together. Alcohol can also contribute to anxiety, so if it applies, it could be something to consider.
Other suggestions I've heard is to be sure you're getting enough potassium, either through your diet or supplements (CHECK with your doctor and medication warnings first though, there are some where extra potassium is dangerous).
How about deep breathing/yoga/meditation?
I had success with acupuncture a while back. Unfortunately I couldn't afford to continue with it. So, if you have the means, it's something you could try.
