My sister was a narcissist,is still a narcissist ,I cut her out of my life for a year and a half now.I reckon she got confused identity wise when I was born.She spent most of our childhood looking at pictures of me as a child and claiming they were pictures of her.

Later when I went to university she started stealing my identity and interests,basically whatever I was into she copied,music,books,politics,she stole my hobbies and used my brain and picked from it to further her own cause of bagging herself a husband.

When I came back from uni ill she had joined all the local political campaign groups I would have wanted to go to and banned me from attending.

She once tried to say she was the one done a photography course I had attended so she could keep photos I took and developed.

She lied about things her whole life,stuff I succeeded in she claimed credit for.At one time she took over my whole identity.

I found out much later when she tried to kill me, drive me to suicide,that she was a narcissist,in my case her motive was money,to inherit my home.

However what I found out about narcissists is they are empty inside, they don't know how to feel,they have no emotions or identity of their own so they steal from and copy others.

They copy their interests and hobbies and they copy them when they show emotions,so they fake love, they fake sorrow,they fake empathy,they fake caring and concern,they fake pretty much all emotions that make us human,they watch real people do it and they copy.

They need us to copy from,give them the goods,we provide their fix and they use us for what they need.

As well as sibling rivalry,narcissists are always jealous,competitive and predatory, when we have sisters who are narcissists we are dealing in danger.

Narcissist will bleed you dry and their ultimate aim is to destroy you to bring about your death in my sisters case to replace me with her by ridding me off the face of the earth was her intention.

I hope this helps those of you who need it to see if your sister problems are as serious as mine were!Marylin
