I am in a similar situation... More to that, I already know I will quit, but still, I have to visit this place for a few more weeks in order to earn some money before quitting (I've lost my savings and my relatives are now unable to help me financially even for a month or so).
It's hard, especially when some of my co-workers are nice and count in me, but the job is just terrible for me...
But on a bright side, when we (me and You) find the job we dream of, we'll feel happy as never due to the contrast) Plus, we'll get some experience here, and You never know, when your skills might be useful)

Wish both of us good luck!
