Can anxiety elevate BP readings?

I am just wondering if anxiety can cause elevated blood pressure readings?
Someone told me that anxiety only effects systolic reading but I’m wondering about the diastolic reading, can that be affected by anxiety too?
As soon as I have to get my BP done my heart races, causing what I believe to be elevated readings – my heart jumps from 72bpm to 120!
Can this cause higher than normal Diastolic?
Once I calm down I’m 110/70 however sometimes whilst freaking out I can be as high as 130/85
Thanks!
