Be careful in how you approach chronic issues like this. Saying the "feeling is not real" is just as dismissive as the doctors in the article. The feelings are real. There just may be no physical cause for them. They are real feelings, perhaps with a psychological or neurological basis.
These people need real help. And that help may be psychological in nature. Don't shame people because of it - support them so they can stand up and accept the help they need.
