There were no hiccups because you did not disclose a potentially disqualifying condition. Being treated with a SSRI medication requires some kind of diagnosis. The FAA assumes that physicians do things correctly. Any condition would require years of SSRI use would be disqualifying until you go through their process. I recommend you ground yourself, find out what the real diagnosis was, and the prepare for a new exam with the FAA to get a valid medical with all conditions fully disclosed. Otherwise this may very well come back and bite you later.
