Hi blackle22 -
If you do a key word search (on this site, use the box in the upper-right corner) on "dry eyes" and another one on "symptom imperative" you'll find plenty of thoughts on both of these subjects.
Everyone here has lots of experience with the symptom imperative, and you obviously already know what it is.
The thing is, you don't need to waste time and energy on specifics. It's really quite unimportant to consider the type of new symptom that might replace an old symptom. All you need to do is accept that each is TMS (which of course assumes that any symptoms of concern are checked out by an appropriate health professional).
So it might be important to you that you read enough descriptions of dry eye(s) from other TMS sufferers that you can accept that dry eyes are probably TMS.
If you ever truly accept the mechanism of TMS, and the reasons it keeps coming back, you won't need to do this in the future. But if you ever truly accept the mechanism of TMS, you won't even bother asking this question, right?
Have you done the SEP or Dr. Schubiner's book? Or checked out Alan Gordon's new Pain Recovery Program? If not, it's probably well past time to do the deeper emotional work! For many of us, especially those of us who land here, the book knowledge isn't enough. But that doesn't mean we require formal psychotherapy - these three self-help resources, along with many others, have helped many people turn the corner.
