I f*cking hate my sister.

It's unfortunate your parents aren't suppoertive. Maybe if you do the work to find someplace for her to go, find out if it's covered by insurance, basically do all the stuff your dad probably just does not want to do, they will agree. Make it really easy for them. Remind them that they are basically dooming her to an unhappy life if they continure to let it continue. I know she is old enough to make her own decisions and ultimately she determines her future, but they can help her make BETTER decisions. Anyone with that much anger and resentment has issues that aren't just going to go away by themself. She needs their help!

OMG that's awful! I wish I had advice, just wow. It sounds like she puts others down because she is insecure about herself.

Michaela: This is going to sound horrible, but I honestly don't have the time to fix her life for her right now. I'm a full time student, full time job, planning a destination wedding, TRYING to work on getting our house fixed. She's a senior in high school and I think that it's high time she gets her life together and handles her own siht. I really don't mean to sound horrible, but I've tried everything to help her. She doesn't want any help, I can guarantee that much.

Hate is such a powerful word. I feel your pain. Your sister is not happy with who she is, so therefore she cannot be happy for you. Kill her with kindness and keep your wits about yourself. Remember it is all about you. Don't let anything nor anyone rob you of your joy.

Bright Eyes- next time she says something- put her in her place. Be firm with her. I'm not talking wedding- I'm talking everything.

Like the deal with your brother- pipe up and tell her that acting that way is not acceptable and you will not tolerate it. She has no right to yell at him, he is free to express his opinion, even if she disagrees and he isn't stupid. However she is rude and her comments are unwelcome.

When she pitches a fit over something- be firm, talk in a very calm tone and don't use curse words. If she starts- tell her to stop acting like a young child and act like an adult if she want to be taken seriously in life. If she escalates it, don't let her get you upset- tell her you will not fight with her, but that behavior will not be tolerated and leave it at that. Walk out of the room.

What she needs is someone to tell her what she is doing is wrong.

Uh ya, sounds a little extreme, like a personality disorder?

Narcissistic Personality Disorder

NPD is characterized primarily by grandiosity, need for admiration, and lack of empathy. Narcissism occurs in a spectrum of severity, but the pathologically narcissistic tend to be extremely self-absorbed, intolerant of others’ perspectives, insensitive to others’ needs and indifferent to the effect of their own egocentric behavior.

Im so sorry... what a sticky situation... but you know what... enough is enough! you know. a woman can only take sooooooo much. I am in a similar situation. keep in mind that no one else's opinion here matters. They have not walked a day in your shoes regarding her... Keep your head up and do not let this brat ruin your day!

I live with one of those It's not easy, but it won't get better without therapy and maybe some meds. Seriously. She needs help.

Do not put her in the wedding, although she has issues and needs help, she doesn't need to able to ruin your wedding. set boundaries and stick to them, people with Personality Disorder need those boundaries are they will spin out of control. I suggest your parents contact a therapist now.

Wow....thats unfortunate.....I'm kinda in the same situation...my sister & I have never really gotten along so we don't speak unless absolutely necessary..everyone knows this. So when I got engaged, my mom asked if she was in the wedding *blank stare* Are you serious? We're not friends & we don't speak....why would she be in the wedding??? My sister hasn't even asked me whether or not she was in the wedding, so why would you?

My mom was talking to FMIL about it & now she wants to speak to me about it...ughhhhh.....

You should have a countdown until the days she graduates high school. then kick that lil bitch's ass out and see how well she does without her family. she'll be wishing she had been nicer when she falls flat on her face.

I feel really bad you are going through this. I just read the post about the X-box...and im just in disbelief.

I think the previous posters are right. Dont have her do ANYTHING for your wedding. Dont have her involved. Dont give her any details. If she comes, great. If not, whatever. But she should NOT be a bridesmaid or have ANYTHING to do with it. Im sorry to say she will probably try 'something" to ruin the wedding if she is in it.....

....My advice would be just dont share anything with her about the wedding period. She needs to be taught that her behavior is unnacebtable. Your parents, unfortunatly, enable her and her behavior. I feel bad for all of you and i sorry about it!

Whatever you do don't include her in the bridal party. She'll make you miserable.

Yeah, wow. Sounds like she needs a beating

I'm sorry Bright Eyes!! I have a 23 year old sister who sounds a lot like that!! yuck... it's not easy to deal with. In my experience, I've learned she just is who she is. She's not going to be influenced by me in any way because she doesn't even realize there is a problem and she's not open to changing something that's not messed up.

The only thing I've found to help the strain in our relationship is to limit our contact. It sucks because it's not what I want, but I just got tired of constantly fighting and disagreeing. Now we talk once every week or so but we keep it short. No talking about major life issues that we'd have problems with...she talks to me about my niece and updates me on things I need to know. I don't talk much about the wedding. It sucks not being close, but I'd rather talk to her regularly and happily than constantly be fighting.

She's immature and not in her right mind- it happens to teenagers. invite her as a guest but don't have her in the wedding party, this is not the kind of person you want close by on the wedding day, while you're getting ready. for dinner seat her with some cousins around her age or something, put them all at 1 table far far away from you and the groom!

I agree with Meghan. You have to be firm with her, but not mean. Tell her that she's not responsible or supportive enough to be the MOH, and if she says she's not coming, just don't react at all. Don't feed her venom. Just say "I'm sorry you feel that way." And don't bring it up again. Odds are she'll probably end up coming to your wedding anyway, because what the heck else is she going to do that day? What drives her craziness is her need for attention, so you just ignore her. That's the only way to make an impact.
