suicide
A yukkuri killing herself, sometimes it's done through eat up easy.
A yukkuri who feels extremely uneasy is unlikely to commit suicide because (1) yukkuris are very persistent beings and an uneasy yukkuri often would still rather try to reattain their easiness (no matter how unlikely it is) than die, and (2) yukkuris already have anti-yukkuritis as an automatic self-killing mechanism when they are truly unable to take it easy.
Therefore rather than caused by being extremely uneasy, suicide on yukkuris are more often caused when they realize that it's impossible for them to ever take it easy anymore. For example: a parent who loses their entire family due to an accident instead of abuse, a nicehead who realizes that they have done an awful thing, or a yukkuri held captive that sees no other way to escape.
