Yes I'm A 65 Year Old Man And Have Panic

Yes I'm a 65 year old man and have panic and anxiety every time I go to the dentist dr or any kind of stressful situation! It's very embarrassing but the harder I try to control it just gets worse! Had a wisdom tooth pulled today and blood pressure was sky high I was so nervous I wanted to run out of the office. Is their any kind of medication for this? Not to take all the time just to get me calmed down for the visit!
