Should I Be Doing Something Else?

I have a hard time relaxing. I'm used to always having something to do, or, more accurately, having TO DO SOMETHING. But in this week off of school before summer classes start, I find myself with the nagging feeling that I'm not getting something done that I should get done. Even when I finish up the stuff I plan to get done, I still keep thinking that I'm missing something. It's really fucking annoying. Just saying.
