specific fic search: trust issues and texting

[whimsys.livejournal.com]

I read this fic a while back and forgot to bookmark it but it's been eating at me--so for whatever reason, John's pissed at Sherlock and wants to punish him, so he ties him to a tree and leaves him there for a while (longer than he said he would).

When he comes back, Sherlock is frightened, yes--but for John. and he's trying to text John to see if he's okay because Sherlock doesn't believe John would ever go back on his word to him.

Cue angst, guilt, uncomfortable feelings, etc. don't remember if it was slash or pre-slash but finding this would be greatly appreciated.
