is that the neighbor you have complaint filed against... the one who was threatening you? or a different neighbor?
i'm sorry about your half-sister... sometimes people seem like they can or want to give more and then it turns out they just aren't up to it. and that hurts. coz usually when we find out is right when we need them.

it has happened to me. i can appreciate how it must feel so isolating too when she is your only family, essentially.
i hope gradually perhaps you can come to understand what her limitations are. then, if you can accept them, you will be able to align your hopes and expectations of her and still have a pleasant rapport, even if it is less close than you would have liked. it takes some time for the hurt to heal though. take your time. it isn't her fault but it isn't your fault either. we all need people. it's human.
thank goodness for the toilet being fixed.
