My sister 'B' has always been extremely difficult. She has been diagnosed with asperger syndrome, and so have I, (it runs in the family) but I feel there is much, much more to her behaviour. The term 'walking on eggshells' pretty much describes how the entire family behaves when we are around her.
On a good day, she is charming, funny and great with my children (she has none of her own) On a bad day she is paranoid and verbally abusive. The weekend ended with her verbally abusing (shouting obscenities) at my very placid DP (after a minor disagreement) and storming out. She also stormed out for half an hour when my nine year old said in a childish way "B is being mean to me" (it was over nothing, and just something a nine year old would say in the playground).
Another melt down occurred when a mutual friend phoned her up and asked to speak to her partner instead of her, she flew into a jealous rage and verbally abused him. I know people would go no contact with someone like this, but I can't. I love her and my daughter adores her. My autistic son also adores her partner. Please can anyone offer any words of wisdom before the entire family falls apart?
