RD i have done the whole confiscated everything and it got to the point all she had in her room was her bed and clothes, no phone, no ipod, laptop etc but it doesnt work with her. I think it was the well i haven't got anything else to lose so who cares attitude.
I once asked LuLu advice last year as i had been reading through her post about her daughter, she had some great advice and helped me ever so much. Do your self a favour and have a look through and read her blog about Belle. I changed my entire outlook on dealing with DD, and to be honest you need to look at this whole situation through her eyes, its a tough time for her and its hard enough being a teen with all the emotions and body changes but then to be moved to a new town where you dont know anyone, it would be a huge change for her. I think maybe if you try treating her in some ways like and adult, even to the extent of having a girls day with her, this was a suggestion form Lulu that really helped my relationship with DD, we have a night once every few weeks where we either go to the movies or dinner, next week i am taking her to get her nails done. Its difficult to find that connection if you are always at each others throats, i now say to DD if she hasnt done what it expected of her " you know that's not really fair that you havent eg hung the washing out as we agreed this is one of your chores" and you know what 9/10 she goes and does it. DD is no angel we have setbacks and usually they around AF time but i cut her some slack as most of the time she is ok.
This weekend she has a birthday party she is invited to and i have said i wanted all her jobs done by friday (tomorrow) or she wont be attending, last night she did the majority and only has a general tidy up to do.
I also think the way you approach the subject with a teen has alot to do with there actions. DH goes at it like a bull at a gate and it doesnt work, i find if i sit and talk about it with her no raised voices etc we can come to an agreement. Sorry if i waffled on a bit.
Good luck having a teen is not easy.
