Weird Mood

So, I'm in a mood.
I don't know why but all day long I've just felt like I wanted to lie down on the floor and just die.
Just quit trying and doing and just lie down and let all of existence pass away from me.
No, I am not suicidal, thankyouverymuch. I'm just in a weird mental place.
I don't know why.
I don't know how long it's going to last.
All I know is that I'm ready for it to go the fuck away so I can get back to my usual happy-go-lucky self.
