if a child died wasa social worker associated wiht the case? has she had any type of psych intervention?

i dont think your sister is nuts - i think she is very damaged and may be doing a lot of this for attention - somtimes people do things for any attention good or bad -

have you sat down wiht your parents - or maybe if you relate more to one than the other andtold them of your concerns and what you know - watch out or they may interpret it as jealousy so make sure you say you are doing this for her benefit as well as everyone elses

she sounds like she has been manipulating people for a while and is used to getting out of trouble - one day it wont work....

lets hope she gets help before that day for both your sakes

let us know how you get on - oh and if you have a school counciller -or college counciller (i dont know how old you are sorry) talking to them may be a good idea or if religious speak to your priest or vicar or whoever it is that you trust

take care and stay safe
