I am sorry for all of your awful experiences! I agree that we sometimes become jaded and are quick to label.
I just had this conversation with a co-worker today. People that come in complaining of fibromyalgia pain often get treated like drug seekers, but because so many people not being legitimate have ruined our perception of it.
It's so hard to figure out if people have ulterior motives, which is sad in itself that we even have to wonder.
We have one woman that comes in all the time, will wait until she has new nurses or doctors and plays them like a string!
Again, I am sorry that you were not treated so fairly in some of your experiences. People make it really hard for us to be compassionate sometimes!
