AN: I've not updated this in so long! Apologies for anyone who's been waiting, sixth form's been insanely busy -_- Anyway, enjoy!
Chorus – Sherlock & John
Tell me how I'm supposed to breathe with no air
Can't live, can't breathe with no air
That's how I feel whenever you ain't there
There's no air, no air
Sherlock feels that his body is letting him down. He knows deep down that he's been neglecting it – forcing himself to continue until he's running on adrenaline like he used to, before John. He hates himself for doing it, but he tries to reason with himself that the sooner he completes this mission, the sooner he can hopefully return to John. However, he knows it would only worry John to see him looking so gaunt, so he makes himself eat every couple of days and sleep before he crashes in order to be vaguely healthy for when he returns. A wry smile contorts his features as he contemplates the idea of a healthy dead man, but he soon shakes the morbid thought and refocuses his attention on the next step of his plan.
Got me out here in the water so deep
Tell me how you're gonna be without me
If you ain't here I just can't breathe
There's no air, no air
John occasionally ventures out of the flat, going through the motions of everyday life in order to keep up the façade that he's coping. He decides to take a walk one evening and is limping along the street when something in his peripheral vision brings him to a halt. He sees a tall figure with blonde curls watching him with concern from across the street, and the admittedly vague resemblance has John's heart beating in his throat. The figure notes John's eyes on him and calls out "You OK mate? Nasty limp you've got there!" The voice makes it clear to John that he's seeing what he wants to see, and after yelling back "I'm fine, cheers for asking though!", he carries on limping towards Tesco. Little does he know, still standing in the same spot, Sherlock is cursing himself for taking such a stupid risk, especially as seeing John limping so badly made he feel even worse.
