I think that the header of this forum in itself may tell some of us something. I think we've brought this condition upon ourselves in some way and it manifested through our lips, whether it was driven by stress or anxiety initially, we keep it going with the negative and constant thoughts. The fact that it is called "factitious" suggests we are creating it, and maybe we are. It couldn't hurt to try and get our minds on other things, i know it is easier said than done. I am finally just getting the idea that maybe we need to just cool it and explore the route of a mental cure.
