The fact that she barely interacted with the cosplay community at a young age and was quasi immediately cancelled (under that old account) says a lot about how toxic she might have been at that young age already. Just saying. Nearly all her tiktoks it feels like she's trying to troll any type of community she went into.
Too bad though, I just feel that with continued ageing/growth she might have found her old behaviour cringe and moved on. What a coward for killing herself. I have very little sympathy and nor should her sister and mother who loved her dearly. In fact even her cosplay best friend was failed by Katie with this action.
