I am actually a bit sorry, I guess I was in a foul mood. I just couldn't relate much to that feeling of entitlement. I don't necessarily think that guy is going through a depression, though.
He did something, it failed. It is normal to be sad about that for a while. No special intervention might be necessary.
I have a deadline and more important stuff to do right now, but seeing your answer and presuming (possibly wrong) that the parent has gone through some sort of "depression", I have to say that these "get over yourself" and "it's all in your head"-type of answers are mightily infuriating. They don't solve anything, they make it worse.
Otherwise, yes, this is a "first world problem".
