stress?

[adsxi]

you're sitting on my chest.
once you stood and walked away,
now you're back and getting comfortable.
my breath shortens and i get dizzy,
i stop believing in what i know
and start following frantic frazzled ideas.
just last week you weren't here,
i jumped and moved and stood up taller.
yet now you're back and how long will you stay?
i feel like you follow me around,
always waiting to see when to pounce.
what can i do to take control of this game?
because i don't know i'll end it like this
get the fuck off me now before i make up a plan
then it's too late and you're in over your head.
