Patient discussion about orphan

Q. What do we do with her? She is an orphan and has only uncle and aunt who don’t want her. I am living with my roommate for the past 1 year. Something strange and new is happening these days. She wanders off somewhere, leaving me guessing. She won’t tell me where or for what purpose she goes. Someone`s valuables are often found in her bag. I am sure it’s been stolen by her. Her contacts with boys have increased and she is regularly going out with them. When I tried to advise her, she started her activities again but on a discreet note. I don’t know what’s happening. Nowadays she remains depressed and sad. She sleeps a lot. She has stopped going for her classes after she had a fight with our classmate. What do we do with her? She is an orphan and has only uncle and aunt who don’t want her.

A. she is a student? if so- any college or university has a psychologist standing by and ready to help in those kind of cases. if not- be a good friend. talk to her, try to show her that her life changed very fast in a very extreme way and she may need help. a psychiatrist maybe..
