Your blood pressure is going up because you are anxious and filled with worry. Any time one becomes anxious there will be an increase in both blood pressure and heart rate.
I understand your concerned because your blood pressure is running higher then what's normal for you but your readings really arent terrible. I think you should stop taking measurements because your anxious, everytime you get a measurement outside of what your used to seeing your gonna get even more anxious which is just gonna cause your blood pressure to go higher as it's a normal body response to anxiety.
You are okay...
