Yes, you should be worried about you BP, you can go to a hypertensive emergency
or urgency, where you SBP is greater than 180 and your DBP is greater than 120(you are really close to get there). symptoms of a hypertensive urgency are severe headaches
, shortness of breath
, and severe anxiety. I wish you would have mentioned a little more about your lifestyle and medication regimen. You are a very young person to have these BP readings, you should take extra care of yourself since you have family heart disease
background. Try to modify your lifestyle the best you can, stop smoking(if you do), exercise daily(unless contraindicated), avoid foods high in salt and fats, and always monitor your BP and follow your medical regimen. Hope everything works out.
