I am teaching and I'm a graduate student; I have three-day weekends every week but have a large pile of things that I need to get done over the course of that time (so it's not really a complete break, it's more that all of the work I can't do because of going to classes and teaching has to be done in those 3 days).  

I find that over my weekends I have a lot of work that I have to do on my own, but I find myself unable to do anything. I sort of fall into a hole. No matter what I do, I can't build the structure. I've done things like forcing myself to go to the gym every day, going to church on Sunday, and hanging out with a friend once in a while. Even though it's better, still I find myself binging and unable to do anything productive. 

Does anyone else deal with this whole falling apart over the weekends? How do you deal with these issues? Also, over the week, I find that I'm so overwhelmed that I am just trying to hold on until the weekend. I feel like I'm white-knuckling through my life. If you identify with this, how do you deal?
