Are you allowed to drive car without meds?

I'm seeing a psychologist. Only seen her twice so far. I hear voices but on extremely rare occasion I'll see something that I now know wasn't real, but to me it looks 100% real. If my psychologist finds out about this then can she require me to be on meds while driving? Is this going to show up on drivers license?

Thanks so much for any help!

have you had a diagnosis? here in the uk you are required by law to inform the DVLA (the driving authority in the uk) of a serious mental illness diagnosis. if you are seeing things it could obviously pose a danger.
