Alone

My truck broke down tonight.  As I was on my way home from an emergency, the intermittent rough grinding noise that I had been telling the mechanics about (but they couldn't recreate) got about 10 times worse and the truck would no longer shift into gear.

I put in a call to my boss, no answer.  Left a message and waited.  And waited and waited.  As I was waiting I had a sobering realization.  Other than my boss, there is not one single person within a 4 hour distance who would actually care that I was broken down on the side of a country road at night.  Not one.

I spend 50-60 hours a week seeing appointments.  I'm on-call for a week at a time, every other week, which means that I spend literally half of my life on-call.  It is not a situation conducive to making friends.

I'm good at my job, but I'm very alone.  Is this what I'm supposed to be doing?  Is this where I'm supposed to be?
