Sit somewhere quiet and take a few minutes to calm down, don't worry about your blood pressure, then take it again. Odds are it will be a lot lower, as will your pulse rate.
My Blood Pressure Reading Is 147/129 Pulse Of 109...I Took It Because I Was Felt Dizzy And Not Quite Well. Should I Worry?
YES! 120/80 is considered normal.
Yes, you should be worried-I strongly recommend you get to a doctor ASAP
