I think this would be the best forum in which to post this topic, since learning about mental illness more always leads to the knowledge that other people do feel like you do. I also find it comforting to indulge my curiosity about this stuff, and figure out some of the reasons why we are the way we are.
Some recent good ones that I'd recommend:
Currently On Netflix:
This Emotional Life
Episode 1:Family, Friends and Lovers (discusses issues of attachment and relationships and the effect of these on happiness)
Episode 2: Facing our Fears (stress responses, phobias and CBT, PTSD)
Episode 3: Rethinking Happiness
Stress: Portrait of a Killer
The Ghost in Your Genes

This one is a fascinating look at the epigenome and it's effect on us on several levels, one of which is our emotional life.
