Hi there...first time caller, long time listener and all that...
Reading your message reminded me of my own experiences. Yes, I've been in the same place...reaching the point where I never wanted to write another piece of code again.
What brought me to that point? A horridly poisoned and hostile work environment. The company I worked for (and happily no longer work for) is quite famous for hiring students fresh out of university. Why? Because they can take advantage of their inexperience much easier...you know, get longer hours out of them for less pay simply because the newly graduated don't know any better. In short, the place had all the trappings of a sweat-shop.
I was involved in a certain project with a very unpleasant and demanding boss who never gave me an ounce of praise (but plenty of criticism), who was always criticising me for my hours (I worked the usual 8 to 4:30...but I got much grief because I wasn't "staying late" every single night). Things were unpleasant, to put it mildy.
This experience made me realize something rather important...oftentimes, it is NOT a good idea to seek a job doing something you love. Me, I love programming. Throughout all my schooling my one and only goal was to become a programmer when I got out into the real world. The problem is, the real world can easily poison the things you love. Corporate programming is -not- (usually) fun. You get squashed by deadlines, pressured to work insane hours, and you rarely get to express any kind of programming creativity at all...you're just a code monkey. The art and soul of programming does not usually exist in any corporate environment...it's easy to get sick of it. I got so sick of it I wanted to leave the entire industry behind.
My solution may not be an ideal solution for you...but it works for me. I quit the offending job and found another job doing something that I -knew- I was comfortable with in a corporate setting...it wasn't a programming job, but it was still computer related. I swore to myself that I would never program for a company ever again...leaving me to do all my coding alone, in the comfort of my own free time. You know what happened? My desire to program returned...I started having 'fun' all over again doing the things that I love. My creative muse returned from a long hiatus. And, I found that I could actually be happy at work as well (my new company treats me extremely well...not every company is evil).
So, I sympathise...I know what you're feeling all too well. The software 'industry' is completely disconnected from the exciting stuff that lured us all to the computer keyboard so many years ago...you need to protect what you love and don't compromise on that. Ever.
