Hi,
Your little guy sounds *so* sensitive (and smart!)--hopefully not in line for existential depression later in life (I think this is also discussed by Dabrowski but I am not sure).
FWIW, similar to an earlier poster, I heard a segment on NPR recently about U.S soldiers returning home and a program trying to prevent issues/ PTSD. The basic idea was to have the soldiers at the end of the day think about three things that had been nice about that day--it can be very small things. It apparently helps quite a bit with overall outlook (and I have tried it myself, and it works on me a little). Maybe something along these lines would help.
Best of luck!
