Dealing with the stress of more than one job, paying rent, and school

Where do I start, I mean as I write this I'm actually at work until midnight, have no money because it's going towards rent, Haven't eaten all day, and the dinning hall in my dorm closed like two hours ago, along with all the Homework, Extra Credit, and studying that I need to do. I sit here and just don't want to do anything just thinking about the stress of it all. I don't know what to put first in my list priorities that does include having a girlfriend also. Not only am i stressing about that, but I don't even know how my classes are going to look semester since my registration doesn't open until tomorrow morning. I mean I'm full of stress, and just don't know what to do with it other than try to make the best out of it and do my best in completing what I got to do at the highest level possible.
