I don't know and really no one here, without knowing your therapist, can answer. My guess though would be that they would be 'recommending you' to be admitted. They might be required to.
Very briefly, many years ago I confided to someone online that I felt like i wanted to ctb. They called the police who came to the house, talked to me while my parents were terrified, and I had to stay a couple months in a psych ward. They're all different but mine was fine, basically neither positive or negative in result but at least I was essentially somewhere that the pressures and expectations of life were suspended for a while. On another hand they likely have their say of what, if anything they put you on chemically, based on what you said. This was all my experience though, just as I don't know your therapist, got no idea about the facilities wherever you are.
Involuntary admission (fancy term for psychiatric imprisonment or something I guess) has a deserved hatred around here. It's not to say though that being in such a place and speaking to doctors there won't help some people. But that's my guess of what will happen. Might be a good idea regardless imo.
I'm curious to see if people with more therapist experience chime in - I have almost none and was never honest with them anyway. Which was probably dumb!
