thank you all for your input and empathy.

There are ebbs and flows to this behavior, and frankly, I'd forgotten about it because she's functioned/managed quite well for several years after a serious event that triggered this. It's sort of like she's kept it under wraps.

But now some big changes in her life loom (not necessarily negative, just big job-related ones) and it's come out in full force. I am, of course, concerned as she ages what this may mean. Yes, I do think it is a way to deal with stress, @sugarbeeme.

The idea to approach her family doctor (whom I know) is a good one that I will keep in my pocket should the need arise.

Thank you again.
