Feeling sluggish , unmotivated and depressed

[Nagma]

I have tried to workout by force , i drank a cup of coffee just before hopping it would wake up . 

My body just refused , i wasn't able to do 30 crunches without burning all my will power into pushing my lazy body . 

Just what the fuck , i slept 9 hours and have a healthy diet , why is this happening ? 

Also , last week after work ( finished at noon ) i just fell  into my bed took a 4 hour nap and then slept at night .
