I am sure that you can overcome this pain. Despite what the doctor said, it is your organism, anf so many things including your condition depends on your emotional state and your mood. What you are experiencing now is really hard, but be sure, it is going to be better! Stay positive and determine that you can overcome everything! Your inner feeling is very important now.
Emily, thanks for being a positive force here; it is appreciated.
I feel, however, a need to temper what you are saying just a bit, so forgive me for doing so but I think it is important.
It may be setting up a person for terrible disappointment and feelings of inadequacy if you tell them that what they are experiencing is definitely going to get better, and that with positive thinking they can overcome anything.
That's not true across the board for everyone. Many people in this forum, including myself, have done a lot of work to alleviate and manage the symptoms of FM, including having a positive attitude toward it, but no one here has been able, with positive thinking, to overcome the syndrome. Many people won't get better, and none of us can promise that they will.
Medical conditions don't depend on a person's mental state and mood. There are hundreds other factors that influence these conditions. To be sure, having a positive approach and attitude can only help, and it is one of the things I encourage all the time. But it won't cure someone, if they have a chronic physical medical condition. Those it does seem to cure are in a tiny minority, who may not have had the actual medical condition in the first place. No studies have been done on this that give reliable information.
The problem with telling someone they can get better by thinking positively is that when they put their heart into doing that and it doesn't work, that person will feel they are doing it wrong or are inadequate to help themselves, possibly bringing about great disappointment, despair and depression. I know this because I have gone through this. It is much more helpful to people to say, quite accurately, that having a positive attitude is a useful thing that can help, and probably never hurts.
