I have health anxiety and OCD. I feel I need to check my blood pressure and heart rate anytime something bad is on my mind. 120/80 unless panic attack?

Alone is hard. dealing with this alone isn't working. A psychiatrist should be able to help. Toughingg it out doesn't get you points - only pain. You've been trying. time to bring in an ally.
I'm not sure about. Your question?? Checking and body scanning are typical signs and symptoms of OCD that is health related and hypochondriasis. However, 120/80 is normal blood pressure, but may change after exercise, stress, and yes panic. It should recover to these levels soon after.
