DD's angry

Now dd is angry wif me..saying that I am not supportive of her and keep scolding her...Nv understand her predicament etc...
Truth is in fact I did ok...I noe her mum is like that but the best way to keep her from doing all these stupid things is not to give in to her let them noe that u are firm then they will noe u can't b pushed...
I just dun understand why she can't see the whole picture, the bigger picture...I am not trying cause a rift in her family but if she keeps giving in like that then there will be no end to trouble only when the other party noes u can't be pushed around then the whole thing will stop.
I dun understand why she cannot realise that everything is for her own good... Not that I feel totally right, in fact I do agree that mabbe my tone was slightly harsh but it's all due to the fact tat I am concern for her...afterall the blog was written when I am terribly upset due also to the fact tat cos of the stupid car thing I didn't managed to meet her today and waited like an idiot the whole day.
I think the best way to help her is to help and advice her to make the correct decision, not to just blindly support her in everything she does.If that's the case then i would be nothing more than a pet.
I dun understand why I must also b the lamb that's sacrifice, everytime she will take the side of her mum/relatives but never on my side, u called that same freq?
If she wans to be angry I also can't do anything.
SighZzz...
