I've been a ball of stress lately and my blood pressure is through the roof. It is taking a toll on my body. I've been exercising and trying to calm down but it doesn't seem to be having much of an effect. A couple times I thought I was having a heart attack and got excited to finally die but it turned out to be nothing.
Are there other methods to lower blood pressure? Any foods?
Something like a change in attitude. Talk with your wife about it openly, because some stress may occur due to the high expectation (you think) she has from you. It's a temporary situation, and it will get better (I assume), so assure her that you work on that, but that the stress is killing you physically. She may even support you somehow.
Not sure how your relationship with her is though, but anyway, don't appear weak, helpless or hopeless.
