Well, you are stuck with a way of looking at it that isn't working, so you could try out some new perspectives. (I have only mine to offer of course.)

What is your goal? Does school have a meaning or purpose to you?

What kind of pain is it? Is it all pain? Right now I have to study first for a mickey mouse course that was crap because of the instructor's poor English and I kind of resent the whole process of having to memorize little bits of nothing and not really have any basic mastery of a subject despite having attended all these lectures and done the stupid labs as well. So I don't feel good about this one. Then I have two serious and heavy courses to slot in to my workload of study, so I had better get the stupid one done so I can do a great job on the two meaningful and valuable courses.

So, what is your pain, fellow student?

Edit: okay, I reread your first post, and there are emotional and mood issues. I am so used to those I just keep marching. Doesn't help you, that approach, but you could promise yourself to take care of those after exams. And also be nice and giv e yourself something good each day, if you can think of a way to do that. (I find that hard also. Though I am surprisingly enjoying feeling good after my new compulsory ankle rehab swim program. So maybe try something good for you? Shifting the funk a bit might get you moving.)
