Hey there.
I don't know how close you are to her, but I suggest trying to talk to her seriously. Not during lunch time or similar, but a proper talk. Ask her why she behaves this way (probably because she is feeling lonely and seeks affection). Teenagers are difficult with their emotions.
She needs to become more confident. There is always a place somewhere to belong and you can be happy without having anything. There is nothing to lose in life. Being overly anxious and afraid of being alone will only make it worse. So perhaps tell her not to worry and, if you're up for it, offer your companionship.
If she won't open up to you, then there isn't much you can do, but stand on the sidelines and wait for the drama to start. So that you can try and catch her when she needs it.
Hope this helped and good luck.
