As of two days ago the sister convinced the mum that by asking social services for a family meeting regarding a care package for when she comes home and discussion regarding nutrition I specifically was too aggressive and now the mum doesn't want anything to do with us. As far as we are concerned we are done with it all and have washed our hands of it. The sister has her own business where she is not home for weeks at a time so her involvement is ridiculous but we have decided that we will have nothing to do with anything going forward. The mother has sided with her precious daughter and we are leaving her with that decision.
Personally I can't even look at the sister's face but I know the best thing is to get gone and we will do that as soon as we can financially.
