Chances of passing financial aid appeal?

This semester I haven't done so great, first off the reason I fell behind in school is because I got a job that a department of the university sent a email out about saying this company was looking for positions, so I put on for it and I ended up getting this job, they did tell me when I interviewed that there was MANDATORY overtime for about 6 more weeks, and I was fine with that because we had a month for Christmas break, and at the beginning of the year the overtime would stop. I got the job mid November and I just quit because it hurt me so bad in school, I wasn't able to keep up and I withdrawed from my math class, got a UW in my art class, D in history, and D- in communications, I went to class but I didn't have time to do homework, I was working from 60-85 hours a week for almost 6 months! But I wasn't making any progress so I got my financial aid denied, but now I plan on working only 20 hours a week so I can focus on school, but now with only 20 hours a week I can afford to pay for school. I'm setting up a academic plan and meeting with counsellors, I know appeals rarely pass for work related stuff, but I was in a tough situation, if I didn't do the manditory overtime then I would have lost my job, and I need something to pay for gas and my car because I have to travel 20 miles to get to school. I'm just wanting to look for some answers and maybe some help to go about this. Thanks!
