That's really the only word to describe it.  I'm physically, mentally, and emotionally weary.  But, if you ask me, I'll tell you I'm "fine."  Because, right now, I simply have to be fine.  I'm clinging...bend till I break Cuz it's all I can take. On my knees I look up, Decide I've had enough. I get mad I get strong Wipe my hands Shake it off THEN I STAND." (lyrics borrowed from Rascal Flatts)
