How to manage the "pain" of misaligned work?

Realizing that the struggle of doing misaligned work is so horrible that it's almost akin to experiencing chronic pain, and yet I have to do several hours of it every day at my job (and I can't just quit right now -- I've got a plan for changing careers, but it's going to take time, and I still won't be able to avoid ALL misaligned work). How do I cope with this?? It almost brings me to tears most days. I can put on music and take frequent breaks, even put on a kids' movie in the background to lighten my mood. But it's still just so awful. Any suggestions???
