Yes, it's possible for anxiety to raise blood pressure up to 190/114.
I wonder why you keep measuring your blood pressure during panic. Try to focus on what you DO know:
1) Anxiety will raise blood pressure in everyone and it is a normal response.
2) Your blood pressure WILL be high during panic.
3) Measuring your blood pressure WILL NOT make it any lower, rather the opposite.
You'll need to work on your anxiety. Labetalol will lower your blood pressure during panic, yes. It may be a good idea, I can't tell for sure because I'm not a physician, but it sounds like the right medicine for anxiety-driven high blood pressure. That said, you need to treat the root, high blood pressure is just a symptom of your anxiety.
I had major "blood pressure phobia". I'm taking SSRI. Fear of high blood pressure is not a phobia. It is actually a manifestation of OCD.
Obsession: My blood pressure is high.
Compulsion: Checking blood pressure, hoping for reassurance.
You can't "avoid" having a blood pressure, you can't escape from your blood pressure. Blood pressure is a perfect thing to fear because you start to fear anxiety (as it will elevate blood pressure). If you were afraid of cancer, you wouldn't have more "cancer symptoms" during anxiety.
You sort of need to be "friends" with your blood pressure. Accept that everyone get an elevated blood pressure during anxiety. And maybe you should discuss medications with your doctor, mainly to treat your anxiety.
