Sister is 7 years older than me. Her behaviour to me since a family bereavement has been appalling. For legal reasons, I've had to continue to interact with her and frankly it has been emotional torture. She blames me for everything that's bad in her life, ridicules my lifestyle, and always puts me last. The last few days have been the final straw. I've carried on being nice to her despite the weeks events but now I know there is an end in sight to us having to interact. After that, she's on her own. I've been close to a nervous breakdown because of her selfish attitude.
