Ativan and birth control pill

I have recently experience high bp that my doctor said was due to anxiety. He prescribed .5mg Ativan. It helped in the beginning but I have now noticed that in only 2 weeks I am having extreme anxiety when it wears off. Last night I woke out of a dead sleep in what the ER doctor said was a panic attack. He then gave me a double dose of Ativan in the ER. This sent my heart rate skyrocketing and caused a major panic attack in the hospital. I have never had these before I started Ativan. Has this happened to anyone? Now they put me on Valium to counteract the anxiety from Ativan. The ER doctor now thinks the high bp was from the new birth control pill I started. I think I am going to quit taking any meds.
