I for some reason have made a friend who CANNOT BE BY HERSELF. EVER.
When someone isn;t she gets scared and comes over She invites herself over . Because she gets so lonely being by herself, even if it is just a few hours. And,she folows me everywhere. She always talks, & never lets me talk at school. She never leaves me alone at school, always needs to be by me in the halls.She texts me every time she's by herself.
She has never experienced some great trauma... she herself says she doesn't know why she gets lonely but she doesn't think there's anything wrong, She told me, I just don't like to be by myself, I don't like being myself

Is something wrong with her? & IS there that is called?
