I hear you, the adult daycare and not being able to leave is definitely not fun. I still think you should consider it if the alternative is worse. In my limited experience in the psych ward of hospitals though, they usually dont keep you for more than a week and if you make a stink about it you could probably be out of there within 3 days. Im not trying to cram my opinion down on you or trying to make you agree with me though. In fact, I remember feeling exactly like you do, even to the point of calling it adult daycare. Even if we cant agree about the hospital part though, to reiterate, you should be able to tell your therapist of your SI. You could even start the conversation with them about where the lines are, which ones you cant cross cause legally then they would have to take action. You can really tell them quite a bit.
