I've noticed this with some of the other students in my class. We started out liking physics and so majored in physics, but now, graduating, have no real interest in physics. One of them has decided to become an actuary, another is going to teach English to kids in China, another is going to math in grad school. I don't know if this was a combination of the bad administration at the school and professors who just couldn't teach or hold our interest or prepare us for harder courses (especially the latter: we weren't taught partial diff eqs or div/curl or eigen____ before they were being used regularly in the respective physics courses). I applied to various top 10 grad schools in physics, but my physics GRE and GPA were pretty bad (I just quit caring about physics the last year of school), and I didn't really want to go to grad school in physics (and it appears I'm getting my wish), but have no clue where to go from here. I don't want to spend the rest of my life staring at code in front of a computer screen (ie running simulations) and I don't think I have the interest/motivation/brain power to become comfortable with previously covered or higher physics at this point. This latter problem is really preventing me from regaining any interest in physics. In the words of Bill Paxton, "That's it man, game over man, GAME OVER!!"
