What does one do when one is training for a job which will require him to drive from venue to venue when he can't understand how he is managing to control a vehicle?

I drove on the motorway the other day, at least I think I did. Cos I didn't really feel any connection between me and the car. I had no emotion towards what I was doing, things that are happening in the world really seem too odd to be actually happening.

My latest problem is also speech. It feels far too automatic, I can't work out how I am shaping words. I feel like the talking is coming from somewhere else, not my brain. Yet sometimes I seem to chat away about things that I'm not even sure exist, and that doesn't seem to be happening to me.

It's like several different people are controlling me or that I'm slipping out of several stages if consciousness.
Help.
