tense nervous headache?

back pains?

lack of concentration?

maybe your parents are coming over...and maybe they're gonna be here tomorrow...and maybe, just maybe, it's just hit you and you're freaking out big time...and maybe you're going to see your counsellor the morning before hand to tell her how you think about death a lot...and maybe she's off on holiday for 2 weeks...

or maybe you've just got a headache. and should stop complaining, read bird by bird..remind yourself why you keep doing all of this nonsense...breathe and just get the fuck through it.
