Having a difficult day

First of all, I should explain a little of what has happened to me to cause me to be disabled.  In 2009, I dislocated my knee, which severed my ligaments, tendons, as well as my peroneal nerve.  My leg is consequentially partially paralyzed, which I learned is called Zenker’s Palsy.  

Today, my church had its food pantry for people in need, and I got to be the intake specialist, which I really enjoyed, because I’m odd and enjoy alphabetising names.  However, my leg is now really very swollen and painful.  I wish it wouldn’t get like this.
