Give it a little time. Call it a mid-life crises if you wish, and ride it out for a while. If you still feel this way in a year, then perhaps you should be flying commercially and might consider a different line of work. Like most professions, driving big airplanes is often routine and often boring, with moments of both terror and great pleasure. If someone promised you life of constant glitz, glamor, bling, the ideal salary and perfect Quality of Life, I think you got lied to - or chose to park your common sense. Slightly more mature thinking may help you.
