1/ I' m looking for this fic where Kurt takes some pills and then calls Blaine. Blaine at the same time calls Finn and they save Kurt. It's pre-slash
2/We see Kurt contemplating suicide several times in MK but every time someone from ND is there to stop him. When he goes home, Finn appears and check if he took any pills. At the end, Kurt escapes and is on a bridge, he is about to take pills when Blaine tells him not to.
EDIT: 1st fic found, but still looking for the 2nd one!
EDIT 2: I found it all by myself (and by accident) the 2nd fic is "lay your weary head to rest"
