Hi kp64
Sorry to hear you are having such a horrible time at the moment, I am exactly the same. I have found CBT and mindfulness to be helpful (I use an app called CALM, its really good although there are lots of other too).
did they find the fibroid/polyp after a scan? If it was two years ago, maybe you have developed another? Is that possible?
Are you on any HRT at the moment? I'm going back to the hospital following a second PMB. First time scan showed nothing untoward, so put it down to hormones. It is scary though,
Take care and post more if it helps
