Christina,
While I can understand your viewpoint, it has been my sense of humor that has gotten me through my illnesses. Without it, I would have been either dead or in an insane ward years ago.
That being said, everyone deals with illness in their own manner. This is just her way of dealing with her PH and it is probably what keeps her sane. This is merely her form of venting and is much more creative than hitting walls or throwing things across the room as I am sure many people do.
I think the timing of this thread is just a little off for you with your current situation and it hits a little too close to home. If you revisit it later in the year you might feel differently. At least, I hope that for you and I mean that in a positive manner. Smiling does make things feel better even for a little while.
