[Qwerty10]

I'm 17, and my sister is nearly 15, and she has been causing trouble in the family for years. She bullies everyone, and can be very manipulative, and yet if other people, such as relatives are around, she is sneaky about it, and denies it when confronted. We also have a younger sister who is 10, and is usually on the receiving end of the violence. Being quite small and skinny, when up against an 11st teen with an obvious vendetta against her, she doesn't have much of a chance to defend herself. Even if either of my parents or myself intervene, we get punched, scratched, kicked, sworn at, and often have things thrown at us (I was hit in the face just recently).

She's been behaving in this way for a long time now, and to compound it all, she steals, not just food, but large amounts of money (£300+ is the largest so far) and is an almost compulsive liar at times. She often hangs around with gangs from other schools when she goes out, has gone through numerous boyfriends (and goes around pretty much asking other guys that she hardly knows to date her on a regular basis, and is often rebuked, therefore gaining her a reputation as a "slag") and has even passed out drunk in a field. I don't deny that my dad used to smack us if we were naughty when we were younger, something that my mum eventually forced him to stop doing, but, like my sister, he has a temper.

My mum, who, like myself, only weighs around 9st, now doesn't even try to argue with her, in case she is attacked, because she doesn't people at her job to "see the bruises". Personally, I would be the opposite, and would enjoy showing off injuries inflicted by her on me to friends and teachers, if only to show people what she's really like. She often threatens us with serious injury, openly laments that we have a younger sister, and tells her that she wishes that she would die. If I get something thrown at me, my sister runs out of the room so I can't do anything back to her. She constantly annoys us, for example:
-running past and turning the TV off repeatedly
-slamming the laptop lid down and locking it
-hitting my younger sister for no apparent reason
-sitting on her (bear in mind how much she weighs)
-blatantly stealing things from us
-going from one person to the next and annoying each one
-holds onto door handles to that people can't get in or out
-stopping someone doing something for no reason at all

I could go on. I really could. I plan to keep a diary, of sorts, accounting for the sorts of **** that she does on a regular basis. I've always believed that she has problems mentally, as I can't imagine a normal person deliberately targeting others than are smaller and weaker than her. Even though she's apparently been to some sort of counselling with my parents, it obviously hasn't worked. She controls every situation, is jealous if me or my younger sister get to do something that she doesn't...

I'm just going to stop now. There's so much that I haven't mentioned, I could probably write a book on her. Maybe I should.

Any sensible ideas are welcome, as nothing else seems to work. I know I've written a lot. When I started, I just couldn't stop.

Thank you for reading.

Wow. I am 25 and my sister is the same age as your wild one. As my mother is a solo parent, things do get pretty tough. Usually though, I sit her down and ask why the heck is she behaving like a brat, and the answer is almost- because she gets no attention. I personally think she has ADD or some hyper-disorder.

Maybe your parents really need to team up and take drastic action- i.e, phsycologist. Maybe she does have a serious mental disorder? Most of the time ecsp with teens these days, it's a lack of discipline and lack of attention. Why don't you suggest a family campout or something? Something that will pull you close together?

Your parents are the parents for a reason- to guide you and discipline you along the way to becoming responsible adults. They should be the ones asking for help- not their 17yo daughter.
