My ds went through the same stage, mainly aimed at his dad. They need to grow apart from you and become independent, and some youngsters get subconsciously very frightened that they won't be able to cope, so they go into overdrive and cold shoulder you completely. Hormones don't exactly help either.
The best thing you can do here is to stay calm and reassuring. Don't show your hurt because to them it will look like "my mum won't be able to cope with my growing up". At a time when they are wondering if they will be able to cope, that is not very reassuring.
Insist on good manners (no name-calling or swearing at you) rather than warmth and engagement. Don't be a doormat or a skivvie, but calmly point out boundaries.
Accept that she needs some space, but obviously keep a weather eye out for any signs of actual depression (extreme tiredness, sudden lack of care for personal appearance, extreme moodiness and despondency).
Assure her calmly and positively that you enjoy having her around. Negotiate how many family activities she has to be part of; insist on a few.
Ds is now 15 and though he still spends a lot of time cooped up in his room he is polite, supportive in an emergency, and will occasionally suggest that we should watch a film together. And he no longer seems to bear the cares of the world on his shoulders. All seems good to me.
