I firmly believe in a connection between intelligence and mental illness. "Ignorance is bliss" comes to mind here. However, I think -- and this is strictly an unfounded hypothesis that simply makes sense to me -- the link depends on the illness.
For example, some mental disease is biological, genetic, chemical/hormonal, etc., whereas others can be brought on by a traumatic life event. The latter is, in my experience, strongly linked to intelligence. I am intelligent. I am also extremely sensitive. I have always had a slight chemical imbalance that, over the years, I chose to treat with behavior-modification therapy (i.e., no pills -- not that there's anything wrong with pills!). But several traumatic life events during my 20s kicked all my issues well beyond overdrive and I was forced to re-think things.
Every time something would happen, I was stunned by the lack of devastation to everyone else. There would only be a handful, if that many, who seemed to be as much of a mess as I was which, of course, got me thinking. And I came to the conclusion that it's not that the dumb ones don't care, but it's as if their mind can only malfunction (for lack of a better term) to a certain degree before, I don't know, I seriously think that some pain is just beyond the level of comprehension in a mind that isn't highly developed, cognitively speaking. That, or I'm just making it all up because I'm totally bitter that I hurt so much sometimes and everyone else seems so functional....
By the way, I'm currently under the care of two doctors and a 3-drug cocktail I take daily upon waking. I am fully in support of pills. And contrary to what some people believe, they don't make me "happy," nor do they Zombi-tize me as my mother would always caution (she was a behavioral therapist; go figure). I'm still the same sensitive, high-maintenance, goofy, quirky, and somewhat odd person I always was with good days and bad days. I still cry (too much in my opinion) and laugh and feel highs and lows and all emotions in between. Actually, I could go for a couple days of Zombie here and there but so far that hasn't been an option. What has changed is that when i open my eyes in the morning, I get out of bed and go about my day. I no longer wake up sobbing uncontrollably and wondering what kind of God wouldn't have had enough pity on me to just let me die in my sleep.... If you wake to the latter, please go talk to someone. No one can fix it but they can make it so it's not so crushing, I promise.
