I have found a recent message to DD(16) from her step sister (17) asking her if she wants to share some weed and to get it from another friend. All 3 are at the same school and 2 are currently in the middle of GCSEs. The school is part boarding and at least one of the them is a boarder (not my daughter).<br><br>I have screenshot the message which leaves no room for ambiguity nor is this a one off. As I understand it, legally both my daughter and her friend would be regarded as supplying. I am very angry with her, she's always been pretty sensible and is doing really well at school. Given the circumstances, I feel school need to know and I know this will mean expulsion, which they are fully aware of. My daughter will be devastated but tough, frankly, she knows the score. While I am fully aware she can get drugs anywhere, I feel that disrupting this rather cosy ring can only be a good thing. l am less clear regarding the other 2 girls.<br><br>As a family, we have spent the last 3 years dealing with the fallout of her brother's drug use and I'm shocked and frankly disappointed that she would go down the same route. With him, I tried the softly softly approach - the timing was similar, I didn't want to jeopardize their exams and, to be honest I felt a deep sense of shame. It didn't work, my son got progressively more abusive, the 'friends' used him and we ended up with both police and social services involvement. We finally seem to be emerging from this nightmare. <br><br>But the thing I'm finding very hard is the sense in which she's manipulated me. I thought we were close but it's clear she's exploited that completely - she would never be like her brother, she's seen the harm it's done etc etc all hiding the fact that she's behaving exactly the same but she thinks she's too clever to get caught. Except she logged on to Facebook on my phone and failed to log out.<br><br>Not sure what I really want from this thread but I can't sleep and needed to get it down. If anyone has any tips or better ideas how to handle this, I'd appreciate your thought.
