Prednisone has the side effect of making you very high strung and jittery, so much so that people often have trouble sleeping while taking it. On top of that, with a stressful week at work, and the other crap we carry around, its no wonder you're down. Give yourself something special and try to hold on till yout T appointment.
"When I was a child
I caught a fleeting glimpse
Out of the corner of my eye
I turned to look but it was gone
I cannot put my finger on it now
The child is grown, the dream is gone
And I have become comfortably numb."Pink Floyd
