I need energy

I have no energy at all today.
I mean if breathing wasn't automatic body function I would be dead already because I just don't want to do anything.
My head is like a heavy concrete cube sitting on my neck.
I am not working today as I told them some lie why I can't.
This day will be really bad. Full of guilt. Full of self shame.
I don't want to be like this. I hate it.
I could just slap myself to move my ass off the sofa.
But moving my hand takes so much energy....
