Thank you! You are right, it's not my responsability but i can't help being worried that she will get hurt when mom and dad are no longer able to take care of her.

We used to be super-close, but as she started this behaviour we have drifted further apart. I last summer was visiting home from college and i confronted her about it, she had a huge tantrum and trashed her room. I apologized because my tone came of as judgemental or catty to her. After this day she blocked me on all social media and stopped returning my phone calls, until now in april when i apologized again. We had a heart2heart and i try to call or text her weekly but she doesn't always respond or call back. Our relationship is not the same, which breaks my heart
