I Have Anxiety And My Blood Pressure Goes Up. I

I have anxiety and my blood pressure goes up. I take ativan .25 twice a day, I take 50 mg of atenol for a mitro vavle prolapse for the past 38 years. I was given lisinipril 2.5 in the past 7 weeks they raised it up another 2.5 and in two weeks my BP dropped down to 80/ 53 ..78 /51 90/54 ect... For a big part of the day. They cut it back to 2.5 once a day but still the same. I feel horrible, no energy,leg feel like giving out,sickly,tired no appetite ect... Now they still want me to take the 2.5 lisinipril and cut the atenrnol to 25 mg. What effect will this have being the lisinipril seems to have bad effects. I am still searching for an antianxiey drug but most make feel bad accept ativan and they really don't want you on benzos
