Really, do I have to put up with this shit?

Just a rant really. Why should I acquiesce to my sister’s shitty behaviour? Why should I always refer to it has ‘her behaviour’ as opposed to ‘her’? Because I’m so f-ing aware that I’ve recognised she can and could change behaviour but not herself. But she f-ing traumatised me as a child ( done the therapy). She continues to behave like a f-ing shit. She’s in therapy which appears to give her permission to carry on like a vile brat.

trying to dialogue with her although I absolutely know that blocking her would be best. Still weirdly deep down want to connect. But I’m just so angry about it all.

caveat: trying to support the management of trauma inflicted on her (now estranged) adult children and my aged parents.

all I want to do is scream and shout at her to try and get her to see sense. I definitely think she’s beyond ND behaviour and well into narcissism or borderline PD.

I absolutely know the right thing to do in this situation. Block, ignore, gray wall etc. but I’m so angry and just want to vent.

Apologies for the crappy grammar, cba.

Just be a grown up and block her. No need to have such drama in your life.

Hope that's helped OP.

What is ND?
What is PD?
You do know you can say "fucking" on here, @FranklyIgiveadamn ?

ND is neuro diverse. You'd better remember that if you intend to spend time in MN (that's Mumsnet btw (by the way)

PD is personality disorder.

My appalling cow of a sister has blocked me and it's glorious. I would have blocked her except that created drama for my mother. Highly recommend NC.

Personally I’d tell her to do one and I’m usually against the whole cutting people out thing! Have you explored why you want to keep in touch?

MegMortimer · 05/06/2026 08:25

A childhood victim of a similar type, OP. NC all the way.

Thanks all. Yes blocked. Everyone else has blocked her too. I absolutely know it’s the right thing and have given that advice to the others before, just struggle to take my own advice sometimes. Mostly I just get on with it. She still turns up on doorsteps though and it’s then I try again to try and explain why her behaviour is so harmful.

the rant was good (forgot to name change!) any way. Thanks all and on we go!

I know i can write fucking. I say it quite a lot but for some reason find it hard to write down. Shan’t be exploring that at all!

Trauma bonding is a thing. You've taken the right action. Don't go back.
