I feel your pain. Thanks for your post in my thread.
That has been the hardest thing for me...the constant back and forth...the constant confusion. They don't know which way is up...they are in so much turmoil it puts your life in turmoil. What can you do to fix them? Nothing I have found...they are living in their own hell...they have probably felt they have been missing something for awhile and this OP fills a void...once that void starts getting filled and satisfied and they start feeling good about something again it seems nearly impossible to pull them away from it. They want more and more...
Good luck in you situation...you have a lot of work in front of you...take care of yourself.
