And you couldn't do or say anything really for fear of being forced to stay longer. After a suicide attempt is the time to engage that person and talk about things, not keep them in a confined space and force them to pretend they're okay so they don't have to stay there for weeks.
This would be my biggest fear about inpatient treatment as well. My reasons are only loosely related, but...
I dated a girl once who had panic attacks, and she had me take her to the emergency room because she couldn't catch her breath. We had no health insurance at the time, so she was asked a rote series of questions by a apathetic doctor in the emergency room, one of which was "have you ever, at any time, considered committing suicide?" Her answer was "Ever? Yes."
With that, we were confined to a 8x8 foot room for 11 hours straight, guarded by a security guard. She was not allowed to leave the room for water or to go to the bathroom, as the hospital, per the very mention of "suicide" was obligated to transfer her to another location for a full psychological evaluation. In that 8x8 room she suffered from many panic attacks afterwards, all of which were witnessed by the security guard and dismissed without care. From the moment the doctors assigned the security guard to watch the door of that small room, we did not see another medical professional again until the paramedics came to force her into an ambulance on her way to the nearest inpatient psychiatric ward.
I'd like to think that this hospital was the epitome of bad healthcare and not indicative of how people with mental health crisis and without health insurance are treated. But, it taught me a lesson insofar as that some medical treatment centers, when faced with choosing between your well-being and guarding their asses in terms of liability, will choose the latter.
If you do choose inpatient care, be very careful how you answer any questions related to suicide or self-harm.
