Hang in there. I work 40+ hours a week and attend school (except in the summer). It definitely isn't easy, but it is something I feel I need to do. Yes, there are days when I just wanna give up and die, but yet here I am.

Like a few others have already said or hinted at, the first week or so at any job can be a bit awkward and stressful. You're having to get used to a new environment and a new set of people, along with all the rules...etc.
