i wouldnt worry until she starts running away or cutting herself. Then i would get more involved. you all need to sit down and actually TALK to eachother and the problem can be resolved.
a few years ago,my drama king of an older brother moved in with my dad and i and tensions were really high,we all sat down and talked about everything and it all worked out.

this is my suggestion. Communication is key to ANY type of relationship. family or other wise.
best of luck!
That does sound like the best solution, what I ended up doing is spending an entire month with my sister, while I was off from my college classes, just sitting back relaxing talking with each other, getting ice cream and having some fun at the beach, what I found is that she was only behaving that way because she wanted to get some attention. She seems to be doing a lot better I just hope she stays that way while I'm gone.
