Well to get the correct diagnosis you need to be 100% honest about what is going on with you and your problems. People here can't tell you what to say to that professional because we are not you going through your day to day life. Just be honest with him and answer whatever questions he/she asks and if you are up front and honest you will most likely recieve the correct diagnosis. Diagnosis techniques and questions are alot different from years ago and more advanced and most times the person who is completely honest and doesn't hide this problem or that recieves the correct diagnosis the first time through.
