I think what I wanted to point out is that people who are prepared to have a discussion need to do a bit of extra work to advertise that they are open for the discussion after the disclaimer

The default internet disclaimer is to tell the person to seek professional help. If you don't have health insurance and can't speak to get an appointment with a psychologists there are services such as the Suicide Prevention Lifeline that you can call in the US under 1-800-273-8255.

It was her misleading way of issuing that same disclaimer. If she was talking to someone else, they might have misinterpreted her completely.

If she generally doesn't feel good about having a discussion but would be willing to have a discussion if a life is at stake than it makes sense to word the disclaimer in a way where someone who's seriously thinking about suicide sees that she addresses the issue but someone who isn't seriously thinking about it, thinks it's a casual remark.
