Hello PandorasAquarium: I'm sorry you are having such a difficult time. I'm afraid I don't have any great suggestions for you. Do you go to these procedures alone? If so, perhaps if there were someone who could go with you to provide support, this might be helpful.
I certainly understand your view of the medical community. I avoid it as much as possible. And, so far, I've been healthy enough to do so for the most part. I'm getting older now though & I presume my good fortune won't last forever.
I hope that your upcoming procedure goes more smoothly than you anticipate. I send warm thoughts your way with the hope that it might be so...
