When i'm having high anxiety bp is 150/98 when i relax it returns to 119/79 range, could anxiety cause such a rise in blood pressure?

Anxiety;BP: Yes, anxiety can impact your bp. Some breath work might help. Look up deep breathing techniques to learn how to regulate your breathing and slow it down. Practice the techniques several times a day, even when you're feeling ok. There are several other relaxation techniques(visualization, muscle relaxation, mindfulness, music, etc), find what works for you.

Agree w Dr Kondilis: You are getting to see the possible physiological effects of anxiety first hand. If you can find a quiet place - do so. Breath in slowly ; deeply through your nostrils. Fill your lungs with air (but not to the point of discomfort). Hold for a count of five then slowly begin to exhale through an open mouth. Repeat at least 12 times, longer if you need to. Get evaluated for anxiety. Take care.

Definitely.: You will want to consult with your general physician, if not a psychiatrist. After that, consulting with a psychologist would be in order to assess the psychological causes of your anxiety and begin developing management strategies.
