Sorry, didn't know where to put this.
My friend (we haven't spoken for ages as she was my lodger as well and took the piss a bit) is now living with a pimp and being prostituted out. She also appears to be on heroin. This is a very vulnerable young woman, her mum and sister have already died from ODs and/or suicide and she's had substance and mental health issues as long as I've known her.
I don't know what to do, she's a beautiful soul and part of me wants to just go round there and drag her out. Should I just mind my own business? She gets obsessed with guys very easily but this is literally a pimp and crack/smack dealer!
