Is your doctor a Psychiatrist? If she's not I would suggest asking for a referral to see a Psychiatrist. Did you ask to go off the meds after 2 weeks? It just doesn't seem to be very long to see if a med was working. I would talk to her about your concerns. Based on her response you will know if she's the right doctor for you. Prior to doing this I would get on a waiting list to see another Psychiatrist (Ideally someone that specializes in mood disorders.) As far as how to do it I would suggest writing out what you want to say and then practice it before your appointment.

I had to google Neurontin because I had never heard of it; I would suggest doing some research on it. Not that wikipedia is the best resource, but this is what was written there:
