Blood pressure 148?

And the nurse at the hospital said it was too high and she asked if I had any pain, which I don't. She wanted to do an ECG but I said no as I wasn't there for anything like that, she said it was too high that's why she wanted to do one. So then a doctor came to see me and asked if I take Beta-blockers, is my blood pressure really that high? I have anxiety and I get nervous! Also I'm 26
