that was not the impression the series of posts made, but in general what you are saying it is true. The choice of words ("cheerful") reflects more on mood than on attitude (optimism is an attitude and cheerful is a mood). So just a lucky mood.

I, in general, like to read about people overcoming struggles. I have read here about a person who peed on herself in bed in such depth of depression that she did not care she stayed in her own piss, and later she did find strength to get up. That is the kind of thing I like to read (and we may majorly disagree on important topics, that is OK). I did not have the impression that OP has such stories to share, but of course I might be wrong. Of course, it is always nice to know that someone has been lucky enough to have been dealt the cheerful side of things.
