Zombie like symptoms

[searchingc]

I have a strange double state of consciousness. When I am asked to think about things in theory I can remember and bring thoughts to awareness and say what I may do, albeit in quite a superficial way. But when asked to bring awareness to reality and my own reality, I go blank and sometimes confused if pushed to do something. I feel like a zombie! I am not lazy-I would dearly like to get feedback from my brain and body. I do not feel it is emotional problem in nature. Could a brain scan shed any light on this? Or some kind of functional imaging? Many doctors think I have depression, but I feel too spaced out for too long for it to be that and I can be cheerful when I am speaking 'in theory'. Could the brain shut-down when faced with reality (I do not feel fear or anxiety just numbness). I can walk and talk but am very cut-off in knowing any internal or external reality.

I would appreciate any thoughts you may have.
