There is a woman we will call Annie who has just moved to the area and she's been at our local pub a few times over the last few weeks, at first she was really funny and likeable, seemed great. We exchanged numbers and were sending jokey texts every few days, all signs pointed to us being on the way to becoming good friends, though it was still early days.
As of last weekend, she started sending really concerning messages about how her depression is kicking in and how she's thinking about getting in touch with her abusive ex - I was taken aback with the change in her messages, but I engaged, I asked if she had access to mental health care, encouraged her not to contact the ex, etc. She was extremely repetitive and needy and just didn't take anything on board that I was saying, and the whole thing was making me uncomfortable, so I started replying once a day or so instead of to every message - and then a couple of nights ago she sent me a message that she was 'finished, not like anyone will care'. So I went over to her flat and made sure she didn't have a specific plan or equipment at hand for suicide and then patted her back for two hours while she cried and finally went to sleep.
She was quiet yesterday, but today the sad, needy messages have started again (20 so far today but no thank you for coming over and sitting with her) and I am not comfortable with this at all. I want her to be OK but this is not a role I'm willing to take on. Does this make me a terrible person? How do I disengage without making her depression worse? I'm not experienced at all with this sort of thing so advice is appreciated.
