Certainly get scheduled check ups and go to ER if necessary.

But...do you think obsessing about it will make it not happen? (Maybe just the opposite as bp can affect it too)
It's ok to be aware and watch for abnormalities but try not to dwell on it. I'm old, and learned that worrying doesn't help at all. Now I'll admit that I don't take my own advice sometimes, lol

Its ok to learn about it (from facts, not self appointed experts). It's good to be informed. But not good to worry about things that may or may not happen.
