When I’ve heard it (it’s been a while), it’s been that they’re concerned I am in a bad enough state that I will hurt myself in some way. I think the purpose is either to get me to reach out to them or to get me not to do whatever. The effect on me has basically been to shrug it off. I tend to assume they are just checking boxes. Otherwise they might actually do something about whatever.

Presumably C’s text precipitated the statement, so maybe you could figure it out from that?
