I have a friend, who has had mental issues on and off for years. She suffered a lot of trauma as a teenager and I think it fucked up her mind. A couple of months ago she told me a story about a party we attended and claimed that all our friends had drugged her, I saw her drinking a lot that night and she vomited outside. She was drunk. She claims she felt out of her mind (she'd just started taking new meds) and that she was drugged. I kind of just brushed off the comment and ignored it. Didn't bring it up. Now she claims that this girl who is so lovely it is unbearable, has been coming to her house and has slashed her tyres three times, tried to steal from her, is jealous of her etc etc. These are claims that I simply cannot believe at all, just like the drugging scenario at the party. She also claims a whole range of other physical attacks that noone has seen or witnessed and she shows no signs of, from this random bunch of people. That her ex bf (whom work with out of coincidence) tried to steal her birth certificate to stop her going to the USA... and other paranoid shit. I spoke to him at work and asked if she'd shown signs of delusional or paranoid thoughts before and he just kinda put his head in his hands and said that once he realised she was schitzophrenic he stopped hating her for everything she'd done to him. He said he'd tried to help her but couldn't. Anyway she's been sending me abusive emails/texts/calls for a couple of days now because I went to a concert and gave a lift to one of my friends, whom she believes drugged her. She's declared that if I don't stop being friends with him I am disrespecting her. How do you tell someone delusional that they are just that? She is not rational right now. I could try telling her Mum but I am not sure how much her family knows about her problems. Her boyfriend is out of the country at the moment. I don't want to just ditch her because of this, we've been friends 12 years but I can't really put up with her dictating who I can talk to either. She needs help but I don't know how to make her see that.
