It's Friday, I'm in...pain?

I always feel like such a lame-o every time I'm the first person who decides to go home from kicking it ("yup-yup", haha). But by the time Friday night rolls along, I feel like I just can't hang anymore. I'm obviously doing something wrong because it's gotten exponentially worse in the past month or so. My body's achy 24/7, and I struggle to keep my energy at a functional level by midday. There's always the weekend to try to recuperate, but it's a continuous cycle because I'd rather fit as much activities as possible on my only free days than spend it wasting the morning/afternoon away in bed. So basically all I want to say is that I feel like shit. Woe is me.
