Congratulations. As you can see in the replies to this thread, not many people posess the willpower to accomplish what you have done. It is admirable to set your mind to something and stick with it. There is nothing wrong with a little bit of dedication. People seem to question if it was worth it or not, but really what did you lose? And at the very least, you gained a sense of accomplishment... and an LD to boot.
Again, congrats.
