I might be going to a psych facility

Hi, I (18f) have been dealing with passive s**cidal thoughts and lately it’s been becoming active. I see my therapist in 2 days and when I filled out the form where you put your behaviors and such into a chart… anyways this is the first time I was genuinely honest. She already has me marked as in crisis but I just would like to know..

If I told my therapist that I am wanting to k*** myself and have a plan, what would be their next step?
