Then why are you crying?

This latest Doctor Who episode really got me thinking about the human psyche and about how complex it is, and maybe Freud really wasn't such a nut.... anyways, it got me thinking about people. Society these days is so unforgiving, and we as individuals are very hard on ourselves... There was this bit in the episode where Vincent and Amy are talking; it goes as follows:
Vincent: ... If Amy Pond can soldier on then so can Vincent Van Gogh.
Amy: I'm not 'soldiering on,' I'm fine.
Vincent: Oh Amy, I hear the song of your sadness. You've lost someone, I think.
Amy: I'm not sad
Vincent: Then why are you crying?
Amy then wipes a tear from her face.

I think that what was said there is a very true reflection of what really happens to some people, the strong people... the people that you always see holding up under the pressure and always offering help to others, the ones that you never see cry. I know that in Doctor Who there are special circumstances surrounding Amy's sadness and her loss of understanding of why she is sad, but i do wonder. I wonder if it is possible for someone to be truly sad but not to really know it. Maybe someone who is so accustomed to being strong and solid as a rock that their psyche tricks them into thinking that they are not really hurt or sad when something happens to them, or in their life. Someone who is so accustomed to being someone else's shoulder that they don't know how to need a shoulder. I think it is possible for someone to cry about something without knowing what it is they are crying about. Maybe there are just some things that hurt so much, too much... so much that our psyche pushes the pain into our subconscious where we don't really know about it. Maybe Freud wasn't such a nut...
