Energy, where are you? Come out, come out, wherever you are!

I just cannot find my energy! It drives me insane! I want to clean the house...and do the dishes...and organize...and go through stuff we dont need and throw it away...but I cant! I have energy on the days I go to work...then I come home and crash. The days I have off I feel like I am just trying to catch up with the rest I didn't get the day before! Today I have had about ten hours of sleep and I am still DRAINED... I went for a walk and helped my friend try to move some light things into her new apartment, I really didnt do much at all...and now I feel like I can hardly function. WILL IT EVER COME BACK?!?!?!?!?!?! Kay...I am gone being fussy...time for some zzz's
