TLDR version: find another job.

If you hate your job, you better leave it. No matter how professional you are, it will show up on your quality of work, you will start slacking off eventually, and it will make you worse programmer than you are now. The fault is entirely on the company who hired you. They've seen your CV, they knew what kind of work you were going to do. I doubt they've even asked about this stuff. So it isn't your fault, and staying at this job will only hurt you. So you should find another job (but be more careful in choosing your next company).
