Gosh.
I'm really sorry to hear your tale of woe. Thanks for sharing it. I've heard and seen it many many times but most Wannabes haven't. It takes bravery to admit in public that you regret something to which you've devoted time, energy and money.
If its any consolation I have known people who've done the whole waiting-6-years-for-a-first-job thing and they made it in the end. It can be done but it is tiresome and you are right in wondering whether it is worth it. Its a repetitive job based on shift work and makes you live where you don't want to live quite often. If there was another job that could pay me as well and didn't involved touching an aeroplane then I'd seriously think about it. And I'm early 30's so not really properly jaded yet.
Best of luck with whatever you do next.
