Me (M,18) and my best friend (F,18) have become friends with Amy (F,17). We do not really like other people, but Amy was recently distanced from her usual group of friends, so we decided to adopt her. Amy is not mentally stable and has dealt with anorexia and depression. It is going better with her now, but she is now going too far into our personal zone:
- Amy shares extremely private information with her parents about us.
- Amy constantly asks about personal stuff that we don't want to talk about.
- Amy cancels her already well-planned birthday party to try to invite us to her birthday party, despite that we have said multiple times that we don't go to birthdays because of religious reasons.
- Waiting upwards of 2.5 hours to bike home with us for only 7 minutes.
- Getting angry when me and my best friend hang out without her.
She has said that me and my best friend are her only real friends, and that she would still have depression and suicidal tendencies, if we weren't there.
TLDR; How do you distance yourself from a emotionally unstable person that has become too attached, without hurting her?
Amy reacts to normal social interactions as if they are extremely weird and awkward. She can talk hours about how someone looked at her funny, while in reality it was just someone that wasn't even looking at her.
So what do we want? We would like to distance ourselves from Amy, to the point were we don't really hang out, but still talk when we bump into each other (We go to the same school, and see each other at least 4 times a week). We're seeking advice how to do this without hurting Amy and while being extra careful because of her mental state and history of being pushed away.
