Diagnosis can take a while. Honestly, be thankful they aren't jumping to a diagnosis and are taking the time to really know you, your moods, your issues better first. Too many times, diagnosis comes too fast and is erroneous which causes a whole other set of problems.

You can approach your questions as "From what you are seeing thus far, where are you leaning in terms of a diagnosis?" You will probably be given their top two or three best educated guesses at this point, and they should be able to explain what they looking for before they can make a firm diagnosis. I know my son's Pdoc is not quite ready to finalize his diagnosis, but he and I have discussed the probabilities and the reason to hold off at this point.
