On "A Plague of Ticks"

This is about the essay by David Sardis that describes what he went through as a kid from early years of schooling through college.  Basically, he talks about what went on in his head on a regular basis.  It was really eye-opening to see what he, and others with obsessive compulsive disorder, go through.  I had no idea it was like that.  I'm not sure what the intent on writing it was.  Did he want to show the hardships people with OCD go through?  Or, was he just telling a story?  Some people called it funny but I see it more as pittiful.  No one should be a prisoner of their own mind like that and I think it was rough to read.  Interesting?  Yes.  But it was still nothing to be taken lightly.
