I was close friends with a girl I used to work with a few years ago. A really great, creative and warm girl a few years younger than me. She was actually my senior in our old role and she was so mature for her age - approachable, just really lovely.
Anyway, she quit her job about 2 years ago because of stress. We kept in touch on and off. During this time the image I had of her kind of shifted - she was quite a big drinker which I didn't expect. She would sometimes turn up to my house for a coffee at 1pm and ask if I wanted to go to pub/get drugs.
Last year she became very unwell. She made some very serious allegations against a mutual friend of ours, and told everyone she was having a baby. She was fully convinced she was pregnant, but the mutual friend was not even in town when she said she had had sex with him. She would send us all baby clothes she wanted in a group chat and refer to us all as aunties. Me and our other work friend encouraged her to take a pregnancy test, but she cut us both off because she said we were "being bitter" and that she didn't need to do that because she "knew" she was. I met up with her a few days before she cut me off, and she was waddling as if 9 months pregnant and using a pregnancy cushion (she must have been, if pregnant, about 3 weeks at this point). She then makes a public status saying she had a miscarriage. We offer support, and then she is radio silent for a year.
She met with our friend in January of this year and told her that she was unwell last year and suffering from bipolar.
She has recently reappeared on facebook posting really upsetting things - that she has been raped multiple times, that she is homeless (she isn't, I have checked with her family), that she cannot have children because of the rape, and that she is going to kill herself. She also posts things about moving away with men she has met on the internet, and very sexual things (this is not her personality). She has shaved her hair off and is wearing very revealing clothes.
AIBU to ask for help on what to do? I think watching it play out on facebook is awful - she has a lot of friends (over 4000) on there and they all must be watching and either thinking she is mad or not knowing what to do either.
I am in no way judging her - MH problems are something i have a good understanding of - I know she is not well. I just want to help in any way I can.
