Downcast and hurting

I have been extremely downcast the last few days. My cheeks sag heavily from under my eyes, dragged down by an invisible weight of discouragement and frustration; it hurts my jaw and face. The corners of my lips droop down forming an ugly upside down 'U' making me look fierce and cold. I sigh heavily very often and my mind is just a blank absent space. I do the barest minimum hoping I don't have any crisis or extra workload to battle with. I just feel so tired of trying . . . working . . . doing and doing . . . endless mindless activities . . . I miss doing important projects, giving life-changing seminars and making an important difference in the lives of people.
