Looking for a specific hurt!Spock fic

[sforthewicked.livejournal.com]

I'm looking for a fic I read possibly on AO3 or the K/S archive where Jim and Spock are a bonded couple and for some reason -a fight or something like that- Jim cuts/blocks Spock off their bond. Spock ends up having a seizure I think and Jim has to go reopen the bond in order to save him. Could have been part of a larger fic but I'm not so sure...
Ring any bells? Please please help...?

Searching for K/S AU Fic

[alethea-dot.livejournal.com]

Hello! I am searching for an AU fic where older teen-about to graduate Spock at the academy starts off as a guardian to younger teen Kirk-I think thir mothers know each other and hence Kirk is left under his guardianship. Kirk grows up desperate to be with Spock but Spock feels guilty because he feels it would be abusing his position as guardian. Kirk still has brief relationships with teenagers/people his own age. Kirk later joins the Academy and rooms with Bones. He dates a Vulcan whilst there and I remember a cinema trip with Kirk, his Vulcan boyfriend, Bones and Spock which is quite awkward.  Eventually Spock realise Kirk is serious and able to make his own decisions now he is older and they get together.  I think maybe the chapters were named after Kirk's age each year?  Any help gratefully received!
