First off, miles dont equal $$$$ as an O/O, accessorials and such make you more, plus percentage pay is usually MUCh better than mileage pay.
For example, I have always made more more money running short loads than long haul. I can do 2 250mile runs at $500 a shot a day, so thats $1,000 in my pocket eachday compared to a 2500 mile run at .90 a mile......
I honestly think you should look into working for a different company. You may be settled in, and know yours runs and lanes, but you seem to be unhappy there. Or just hang it up and go do something else all together....
