Dear Kathryn
I haven’t spoken to you in ages but as it seems I am the first to see this post I will take this as a golden opportunity to catch up.
I think it is common for siblings to find themselves not communicating clearly at difficult times like this when a parent is involved.
I have a little note stuck on my wall that says ‘when someone is determined to find fault with me and judge me regardless of the truth the only way I can win is not to play’. I am not suggesting that anyone is playing but maybe your sister has lost her way a bit and I think it would be good for you to carry on, doing what you are doing, knowing that you are doing everything for the right reason and not dwell too much on the whys and wherefores of her behaviour.
Your sister has been your rock and has been someone you could depend on – look after your mum and do what you have to do and hopefully your relationship with your sister will return as good as it was before.
Don’t try and put your finger on anything – just be yourself and you will be fine.
As Ever
