Your not getting a "Bipolar diagnosis" isnt really important at this point..Trust me you dont want saddled with the Bipolar label unless you really are. I see alot of people with just Depression being put on Lamictal now a days.
If you feel flat or snowed under by all means speak up and tell your Pdoc. Maybe you are on to high a dose or maybe you need something else or maybe you can learn coping skills and handle life med free .. Who knows .. You have many options dont get discouraged.
