I'm really sorry you feel so negatively about the choice you made to certify in coding. I can only say that there may be a lot of the newer coders, and maybe some older ones, who are having difficulty finding jobs, but there are many, many of us working and we do enjoy our careers.
Unfortunately, you do hear a lot about the negative side of certification on here, that's what it's for, to be able to gain advice from those who have gone before. I don't feel we hear enough about the good things that happen though, so it's off-set by negativity. With over 50,000 certified (I believe that was the last number?) you figure the relatively few who are unhappy, that leaves a whole lot of people who are satisfied (if not happy) with their career choice. Make no mistake, there are days when I would say I would give it up in a heart beat, but I wouldn't because I really enjoy the research, the give and take, even the arguing (just to see if I can be right!!!).
The ICD-10 will be just another hurdle/challenge to keep us on our toes. We have to keep our certification up, which means more education constantly, which is why AAPC is one of the leading credentialing sources in the United States. I, for one, do enjoy learning anything new.
So, having said this, just want to let you know, there is always another side. Please don't give up if this is what you want to do. And as the saying goes, anything worth having is worth fighting for! So, if this is truly your career choice, keep fighting!
Best of luck to you!
