So Blarry is depression, and he's all up in your shit. 
People are like "Yeah you just need to excercise and eat well and you'll feel better". 

But it's not really that simple, because you've got Blarry on your back, holding you in bed, telling you to order a pizza.

He's a damn jerk and he doesn't leave. 
No one invited him, he just appeared, and stayed, and made a mess of your whole life. 
God dammit Blarry. 

So you just stay at home with him, because if you go out, he'll probably follow you and you'll have to carry him everywhere, and he is just so, so heavy. 

So it's easier to just stay in bed and eat BBQ shapes for dinner.

That's depression.
