Can severe anxiety cause a rise in blood pressure?

Hello doctor,

I am a 19-year-old male and have been healthy all my life. I do not drink caffeine, I am not overweight, and I have always been active. However, I have always suffered from severe anxiety. For several years now, my blood pressure has been high when visiting the doctor, but he always says it is because I am nervous and there is nothing to worry about. A year ago, I started having panic attacks, and my blood pressure, as checked by the doctor, was 169/110 mmHg. Again he said it was because of anxiety. Ever since that day, I have been obsessed with my blood pressure. I bought a wrist monitor, and even at home, I get nervous, and my blood pressure is 150/105 mmHg. I do not understand why I would have high blood pressure at such a young age. My face gets randomly hot, and my ears, too as well. I hear a heartbeat in my ears when lying down. Is this due to high blood pressure? I need to know if I actually have hypertension or if it is all from my anxiety and constant anxiousness. Kindly help.
