I name changed for this.
I suspect my sister has a personality disorder on the group B spectrum.
For a few years she took situations out of context and jumped to worst possible conclusions that weren't true. Her emotions are intense and dramatic. She's done that to me and tlout other siblings. We all took a step back from the drama because we can't handle the drama. For a few years we've all been on the receiving end of revenge. It looks like she wants us all to fix her and fix her happiness and own our parts in her narratives of the situations, a lot of it is not true. Like she wants me to explain myself to her as to why I'm jealous of her. That was some of the messages I got from her. I'm not jealous of her and I can't explain that and if she believes I'm jealous of her so be it. I really had to take a step back from that as do the rest of our siblings. She's very a hostile person. We don't have time for the drama.
I do suspect that there is something going on. All of this, has been long term. It's not only against the family although we probably received the brunt of a lot of it. She doesn't get on with other people like with her colleagues and she'll go through jobs. Her house shares too. Everyone in her life is the one with the problem in her view and not her. she won't ever look at herself and her own hostility.
Basically going through a very hard time from her. She's not in our lifes any more. She's doesn't bear a presence physically in our lifes any more and it's been a few years since we've seen her but she won't stop pushing herself back onto the family by electronic means. Basically emails. Fakes accounts. Contacting other people and anyone associated with us and basically shaming us and dumping shit to all and sundry.
