DSD - coping strategies?

[BuzzLightbulb]

Picked DSC up last night for their week at ours, 30 seconds in the car and DSD 16 was tearing into her sister with all the venom she could muster as usual.

She'd skipped a day off school with a self diagnosed infection, though the doctor wasn't so sure.

And more stuff, but cut to the chase....

I find I'm on edge all the time when she's around, probably because of recent history but also because of her attitude towards anyone else, her tone of voice, just the way she is with people.

I'm just waiting for her to start the next fight at any moment, which I think is making me gear up for it ready to go.

Atmosphere at home has changed from a lovely relaxed weekend to the usual battle front. DP knows this so has switched to wash over her mode which just bugs me even more.

Any suggestions how I turn my stress tap off? If I go for a walk I get it in the ear from DP for leaving her to deal with things by herself so it'll have to be something which gets me to turn off mentally.

Tried alcohol....

Some teen kids are very difficult to deal with. My dsd1 is 18 and I can relate to what you are saying in your post.

I try and detach as much as possible. I'm polite but I don't try and make conversation with her, there's no point, she just wants to argue anyway.

I think the other way to deal with it is face it head on and treat her as you would your own but if you won't get support from your dp, then you're really on a hiding to nothing and will end up emotionally exhausted.

Get out and get some exercise and some outside support if you can to try and deal with the resentment and frustration.
