My Job Is Bad For My Health

I thought school was bad for my health (all-nightetrs, irregular sleep/eating patterns), but I've never been under so much physical/emotional stress until I started this job. During the first few days of work, I was given such a low, sucky chair to sit in that I started getting backaches and felt like I was developing carpel tunnel. Turns out they had a whole room of good chairs, and never bothered to hook me up until I had to ask. Next comes the absolute exhaustion I've been experiencing ever since I started work. Not only am I commuting approx. 3 hours every day, but in my first week I ended up working 60 hours, not including my 3 hours of tutoring. Even though I do get paid for those overtime hours, it is SO not worth it. Then there's the issue of the office lighting. The lighting is practically non-existent. During the day it's fine since the loft windows are massive and let in enough light. But come late afternoon, it's so dark that the only light around my desk is coming from my monitor. I have no desk lamp, and the company has none to give me. So my eye's been terribly strained for the past couple of weeks and has finally blown up into an infection. OMG. Dying.
