Elizabeth, I do not personally prescribe this medication, but if your doctor gave it to you for seizures, it will have a mood stabilizing effect since most seizure medications do, and some have even been adopted for bipolar. But the fact that it works for you does not mean that you are bipolar. On the other hand, if your mother is bipolar, it may work for her just because it works as a mood stabilizer. I don't know anything about the frequency of psychosis and doubt that is common. You can ask that question of your doctor, the pharmacist, or the manufacturer.
