Suggest Medication For High Blood Pressure Due To Anxiety

Hello Samuel kevin here. Thank you for listening to me.Should I be worried about my blood pressure? I am 69 years of age and I have been treated for blood pressure for many years.I take 2.5mg of Cilazapril(Zapril). I take my own readings and over the last 6 months or so have noticed my bottom line creeping up into the mid 80s and sometimes into the mid 90s.The top line is round the 125/135.I watch my diet and I am of slim build and I walk most days. I also have taken Doxepin for 20years(75mg) for anxiety, the aftermath of a marriage split. My anxiety over the last few months has increased after having been acceptable for many years and I do think this has been the cause of my elevated blood pressure over the last few months.My quality of life has not been good with the added anxiety and it could be that the dosage of Doxepin needs to be increased which may contra the added anxiety and in turn lower the blood pressure? I am aware of the toxic aspect of Doxepin along with the addiction aspects but at my age? Should I worry too much? What do you think would be the most appropriate way to handle this? Kind Regards....................Kevin.
