See if you can convince her to write down her predictions in a calendar, like “by this date X will have happened”.
You can tell her that she can use that to prove to her doubters that she was right and she called it months ago, and that people should listen to her. If somehow she’s wrong, it can be a way to show that all the things that freaked her out months ago never happened and she isn’t even thinking about them anymore because she’s freaked out about the latest issue.
