frustration from the news is playing a part, then just go into the other room if your GF wants to watch news, read a book, listen to music, take a nice walk, and see what happens.
However, it seems you are saying your systolic has been trending up, and it might not be prudent to just write it off to being frustrated with the news.
Consider a consult with your physician, perhaps have some blood work done to check kidney function, lipids, and other parameters, etc.
As people get older peripheral resistance can increase, and systolic can become much more of a factor than the diastolic. The pulse pressure, (the difference between the systolic and diastolic), reflects this.
They may need to add another BP med or increase the one you are taking if reasonable measures don't seem to be controlling your systolic readings.
I wouldn't ignore it though, and discuss it with your physician, especially in regard to the new BP standards which were based on a large randomized trial.
