AIBU to ask for help?

[user1471444904]

I have 12 yr old twin girls who are the most badly behaved, ignorant kids I have ever encountered!
It’s got to the point where I hate them coming home from school. I know the second they walk through the door the bitching, arguing and constant back-chat will start. It doesn’t matter what punishment is given, I try grounding them or taking away electronics etc but they don’t care. It’s just relentless .
No one would believe that we have older children, 6 of them in fact! none of them have ever acted as badly as these two.
Does anyone out there know what I can do? This is getting to the point where I feel like walking out and never coming back.

Typical teen girls.

Presumably there is something more going on if they're the most badly behaved kids ever?

What specifically are they doing that needs punishment?

My current train of thinking is to leave the room! Dd's are 12+13 and torturous!!
Just threatened to not go on the up and coming trip and send them with df!!

As I said we have others, 3 more girls and 3 boys to be precise, all older. but never had behaviour this bad. One is just destructive and the other is so spiteful.
And nothing going on either, no family problems, enough money for them not to miss out on the occasional holiday or big treats. All fine with school....

I think it's probably just teenage stage but MAYBE a generation thing as well. UANBU to ask for help if you think you need it x
