What testing have they done that backs up their opinion that makes them certsin they are right? Maybe you should get a copy of the documentation they are using to base their opinion to that yiu will understand them better & not just be contradicting them because it is how you have felt all your life. If researching their basis still leaves you wondering not just because you have your mind made up but because there are actual facts that cause doubt then by all means.....GET A SECOND OPINION!!!!
