line in the sand is that each location and mental health agency has their own rules about this kind of thing.

to find out whats what on this where you are you will need to contact your medical doctor or a mental health treatment provider who can tell you what the laws and mental health protocals where you are stands on this issue.

here where I am if a treatment provider feels the person is going to act on their thoughts they must be hospitalized to go through the assessments for whether the person is really a danger to their self or others. but otherwise thoughts are ok actions are not here where I am located (NY state)
