It is really ignorance of doctors that keeps the practice continuing. I strongly suspect this doctor truly believes what he is saying and believes he is not causing serious damage. Of course, he is absolutely wrong but the idea that he is doing this out of ignorance versus malice may help you to move on. You cannot turn the clock back and even if this doctor would understand what he has done, you are still in the same situation. Focus on what you can do in your current situation to heal as best you can and to improve the quality of your life.
