Since this happens when you are alone, I'm not sure whether you mean literally speaking or perceiving your own thoughts in these distinct ways. It sounds like it may not be easy to reconcile these different aspects of your personality. If this gets more intrusive in your life, it may be helpful to lower the dosage of Prozac. I am bipolar and taking lithium. Even though it has kept me out of the hospital for 9 years, I've been cycling lately and hesitate to take Paxil because of the side affects.
All antidepressants have the potential of increasing cycling.
One question is whether the cycling only started after Paxil. If so, it would help to taper and stop the Paxil. Another possibility would be the addition of another mood stabilizer to the lithium. I is people who at some time had a full manic episode, in terms of the symptoms, impairment or problems, etc. I would think this is especially difficult, because the patients think they know more than the doctors do.
